A formula for node A's average throughput can be expressed as: T_{a}= Gp_{a}(1-p_{b})^{G-1}Here, p_{a} is the transmission probability of node A; p_{b} is the transmission probability of node B; and G is the number of active nodes competing for the channel.
The total efficiency of the protocol with these two nodes can be defined as the sum of their average throughputs. Therefore, efficiency T_{a} + T_{b}. In the slotted ALOHA protocol, the efficiency of the protocol is equal to the average throughput achieved by the nodes. The throughput of node A can be expressed as:T_{a} = Gp_{a}(1-p_{b})^{G-1}Where G is the number of nodes that are active and competing for the channel. Since node A has more data to transmit than node B, the transmission probability of node A (p_{a}) is greater than that of node B (p_{b}).
The throughput of any other node can be expressed as:T_{b} = Gp(1-p)^{G-1}The average throughput of node A can be calculated as the ratio of the number of slots that node A transmits a packet to the total number of slots. This is given by:T_{a} = 2Gp(1-p)^{G-1}The average throughput of any other node can be given as:T_{b} = Gp(1-p)^{G-1}Therefore, the expressions to compute the average throughputs of node A and of any other node are:T_{a} = 2Gp(1-p)^{G-1}, andT_{b} = Gp(1-p)^{G-1}.

true/false: bubble sort and selection sort can also be used with stl vectors.
True. Bubble sort and selection sort can indeed be used with STL vectors in C++.
The STL (Standard Template Library) in C++ provides a collection of generic algorithms and data structures, including vectors. Vectors are dynamic arrays that can be resized and manipulated efficiently.
Bth bubble sort and selection sort are comparison-based sorting algorithms that can be used to sort elements within a vector. Here's a brief explanation of how these algorithms work:
1. Bubble Sort: Bubble sort compares adjacent elements and swaps them if they are in the wrong order, gradually "bubbling" the largest elements to the end of the vector. This process is repeated until the entire vector is sorted.
2. Selection Sort: Selection sort repeatedly finds the minimum element from the unsorted portion of the vector and swaps it with the element at the current position. This way, the sorted portion of the vector expands until all elements are sorted.
You can implement these sorting algorithms using STL vectors by iterating through the vector and swapping elements as necessary, similar to how you would implement them with regular arrays. However, keep in mind that there are more efficient sorting algorithms available in the STL, such as `std::sort`, which you might prefer to use in practice.

The solution to create a standard main method:```import java.util.Scanner;public class MyClass { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); int[] num = new int[3]; System.out.print("Enter the first number: "); num[0] = scanner.nextInt(); System.out.print("Enter the second number: "); num[1] = scanner.nextInt(); System.out.print("Enter the third number: "); num[2] = scanner.nextInt(); int sum = num[0] + num[1] + num[2]; int average = sum / 3; System.out.println("The sum of the three numbers is " + sum + "."); System.out.println("The average of the three numbers is " + average + "."); }}```
We first import the Scanner class to get user input from the command line. We then create an array of size 3 to store the 3 integer inputs. We then use the scanner object to get input from the user for each of the 3 numbers, storing each input in the num array.We then calculate the sum of the 3 numbers using the formula num[0] + num[1] + num[2]. We also calculate the average using the formula sum / 3. We then use the System.out.println() method to print out the sum and average of the numbers to the console.Remember that computers aren't clever, so we have to make sure we are using the correct data types and formulas to get the desired results.

This question is about a computer system which allows users to upload videos of themselves dancing, and stream videos of other people dancing. This is a critical system and downtime of the service should be avoided at all costs. Your job is to add a new feature to the platform. Since you are writing it from scratch, you decide this would be a good moment to experiment with Unit Testing. (a) Referring to the Three Laws according to Uncle Bob, and a Unit Testing framework you have studied on this course. Describe the workflow of Unit Testing.
Unit Testing is a software development practice that involves testing individual units or components of a computer system to ensure their correctness and functionality.
Unit Testing is an essential part of software development, particularly when adding new features or making changes to an existing system. The workflow of Unit Testing typically follows three main steps: Arrange, Act, and Assert, as outlined in the Three Laws according to Uncle Bob (Robert C. Martin).
The first step is to Arrange the necessary preconditions and inputs for the unit being tested. This involves setting up the environment and providing any required dependencies or mock objects. It ensures that the unit under test has all the necessary resources to function properly.
The second step is to Act upon the unit being tested. This involves executing the specific functionality or behavior that is being tested. It may include calling methods, invoking functions, or simulating user interactions. The goal is to observe the output or changes caused by the unit's execution.
The final step is to Assert the expected outcomes or behavior of the unit. This involves comparing the actual results with the expected results and determining if they match. Assertions are used to validate that the unit's functionality is working as intended and that it produces the correct outputs.
By following this workflow, developers can systematically test individual units of code and identify any defects or issues early in the development process. Unit Testing helps ensure that the new feature or changes do not introduce any regressions or break existing functionality, thereby maintaining the critical system's reliability and avoiding downtime.

How can telephone lines be used for data transmission?
Why does ADSL2 perform better than ADSL over short distances but similarly over long distances?
What is Vectored VDSL? How did cable TV operators become internet service providers?
How do optical fibre cables augment DSL systems?
Telephone lines have been used for data transmission for many years. The telephone line's twisted-pair copper cables are suitable for data transmission because they have low noise interference and adequate bandwidth.
With the introduction of digital subscriber line (DSL) technology, data rates in excess of 8 Mbps over a standard telephone line were made possible. The DSL technique operates by using the higher frequency ranges of the copper telephone cable, which are not used for voice communication, to transfer data. DSL technology is now used to provide high-speed internet access to residential and business subscribers. the data rates available over a telephone line were limited to only a few hundred kilobits per second until recently.
ADSL2 performs better than ADSL over short distances because of the better modulation techniques that ADSL2 uses. ADSL2 uses a modulation technique called DMT (Discrete Multi-Tone) that is far more robust than the modulation technique used in ADSL. DMT divides the available bandwidth of a channel into 256 different frequency bins or tones and modulates each of the tones with data to achieve higher data rates. Vectored VDSL is a technology that uses the signal processing algorithms that enable each line to be analyzed to reduce crosstalk, which is a form of interference that occurs when signals from adjacent lines interfere with each other.

Lab 03: Scientific Calculator Overview In this project students will build a scientific calculator on the command line. The program will display a menu of options which includes several arithmetic operations as well as options to clear the result, display statistics, and exit the program. The project is designed to give students an opportunity to practice looping. Type conversion, and data persistence. Specification When the program starts it should display a menu, prompt the user to enter a menu option, and read a value: Current Result: 0.0 Calculator Menu 0. Exit Program 1. Addition 2. Subtraction 3. Multiplication 4. Division 5. Exponentiation 6. Logarithm 7. Display Average Enter Menu Selection: 1 If an option with operands (1-6) is selected, the program should prompt for and read floating point numbers as follows: Enter first operand: 89.1 Enter second operand: 42 Once the two operands have been read, the result should be calculated and displayed, along with the menu: Current Result: 131.1 Calculator Menu Operational Behavior This calculator includes multiple behaviors that are unique depending on the input and operation specified; they are detailed in this section. Exponentiation For exponentiation, the first operand should be used as the base and the second as the exponent, i.e.: If the first operand is 2 and the second is 4…2 4
=16 Logarithm For logarithms, the first operand should be used as the base and the second as the yield, i.e.: If the first operand is 2 and the second is 4…log 2
4=2 (Hint: Use python math library) Displaying the Average As the program progresses, it should store the total of all results of calculation and the number of calculations. Note that this does not include the starting value of 0 ! The program should display the average of all calculations as follows: Sum of calculations: 101.3 Number of calculations: 2 Average of calculations: 50.15 Note that the average calculation should show a maximum of two decimal places. The program should immediately prompt the user for the next menu option (without redisplaying the menu). If no calculations have been performed, this message should be displayed: Error: no calculations yet to average! Extra Credit Using Results of Calculation You can earn 5% extra credit on this project by allowing the user to use the previous result in an operation. To add this feature, allow the user to enter the word "RESULT" in place of an operand; if the user does so, the program should replace this operand with the result of the previous calculation (or zero if this is the first calculation): Enter first operand: 89.1 Enter second operand: RESULT Sample Output Current Result: 0.0 Calculator Menu 0. Exit Program 1. Addition 2. Subtraction 3. Multiplication 4. Division 5. Exponentiation 6. Logarithm 7. Display Average Enter Menu Selection: 7 Error: No calculations yet to average!

Exponentiation 6. Logarithm 7. Display Average Enter Menu Selection: 5 Enter first operand: −2.0 Enter second operand: −2.0 For EC, replace with RESULT
To implement a scientific calculator on the command line. The program should display a menu with various arithmetic operations, options to clear the result, display statistics, and exit the program. The calculator should prompt the user for menu selections, operands, and perform the corresponding calculations. It should also maintain a running total of calculations and display the average when requested. Additionally, there is an extra credit option to allow the use of the previous result in subsequent calculations by entering "RESULT" as an operand.
The scientific calculator program begins by displaying a menu and prompting the user for a menu option. The program then reads the user's selection and performs the corresponding action based on the chosen option. If the option requires operands (options 1-6), the program prompts the user for two floating-point numbers and performs the specified arithmetic operation. The result is displayed along with the menu.
For exponentiation, the first operand is used as the base and the second operand as the exponent. The result is calculated accordingly. Similarly, for logarithms, the first operand is the base and the second operand is the yield.
To display the average, the program keeps track of the total of all calculation results and the number of calculations. The average is calculated by dividing the sum of calculations by the number of calculations. The average is displayed with a maximum of two decimal places.
If the extra credit feature is implemented, the user can use the previous result in an operation by entering "RESULT" as an operand. The program replaces "RESULT" with the result of the previous calculation, or zero if there have been no calculations yet.
The program continues to prompt the user for menu options without redisplaying the menu until the user chooses to exit. If no calculations have been performed and the user requests to display the average, an appropriate error message is displayed.
Overall, the program provides a command-line interface for a scientific calculator with various operations, statistics tracking, and an optional extra credit feature.

in the run-mode clock configuration (rcc) register, bits 26:23 correspond to the system clock divisor. what bit values should be placed in this field to configure the microcontroller for a 25 mhz system clock?
The specific bit values for configuring the Run-Mode Clock Configuration (RCC) register to achieve a 25 MHz system clock depend on the microcontroller. Consult the datasheet or reference manual for accurate bit values.
The bit values that should be placed in bits 26:23 of the Run-Mode Clock Configuration (RCC) register to configure the microcontroller for a 25 MHz system clock depend on the specific microcontroller you are using.
Let's assume that the RCC register uses a 4-bit field for the system clock divisor, with bit 26 being the most significant bit (MSB) and bit 23 being the least significant bit (LSB). Each bit represents a binary value, with the MSB having a value of 2^3 and the LSB having a value of 2^0.
To configure the microcontroller for a 25 MHz system clock, we need to determine the divisor value that will result in a 25 MHz frequency. The divisor can be calculated using the formula:
Divisor = (Clock Source Frequency) / (System Clock Frequency)
In this case, the Clock Source Frequency is the frequency of the source clock provided to the microcontroller, and the System Clock Frequency is the desired frequency of the microcontroller's system clock.
Let's assume the Clock Source Frequency is 100 MHz (this is just an example). Using the formula, the divisor would be:
Divisor = 100 MHz / 25 MHz = 4
Now, we need to represent this divisor value in the 4-bit field of the RCC register. Since the divisor is 4, which is represented as 0100 in binary, we would place these bit values in bits 26:23 of the RCC register.
Again, please note that the specific bit values may vary depending on the microcontroller you are using. It's essential to consult the microcontroller's datasheet or reference manual for the correct bit values and register configuration.

early networks did not resemble the networks in use today because they were mainly proprietary and performed poorly compared with today's deployments. A) true b) False
True. Early networks differed significantly from today's networks as they were primarily proprietary and had inferior performance compared to modern deployments.
The statement is true. In the early stages of network development, networking technologies were largely proprietary, meaning that different vendors had their own unique protocols, architectures, and hardware implementations. This lack of standardization made it challenging for different networks to interoperate effectively, leading to limited connectivity and compatibility issues.
Additionally, early networks often had limited bandwidth, slower transmission speeds, and higher latency compared to the networks used today. These performance limitations were due to the less advanced hardware, inefficient protocols, and less optimized network infrastructure that were available at the time.
Over the years, with the emergence of standardized protocols such as TCP/IP and Ethernet, along with advancements in hardware and network technologies, modern networks have become highly standardized, scalable, and capable of delivering significantly higher performance, reliability, and efficiency. Today's networks support a wide range of applications, offer faster data transfer rates, and provide seamless connectivity across diverse devices and platforms.

which one is it
When using keywords to search library databases, it's important to try using synonyms and related terms. Different keywords, even if they mean the same thing, will often give you back different results.
When searching library databases, using consistent search terms (option 1) is not always the most effective approach. Different databases may use different terminology or variations of keywords, so it's important to be flexible and try using synonyms and related terms (option 2). By expanding your search vocabulary, you increase the chances of finding relevant resources that may not be captured by a single set of keywords.
Searching the library database using whole sentences (option 3) is generally not recommended. Library databases usually work best with individual keywords or short phrases rather than complete sentences. Breaking down your search query into key concepts and using relevant keywords is more likely to yield accurate and targeted results.
Regarding option 4, the use of operators like "AND," "OR," and "NOT" can be beneficial for refining search results by combining or excluding specific terms. These operators help you construct more complex and precise queries. However, it's important to use them appropriately and understand how they function in the specific database you are using.
In conclusion, the most important strategy when using keywords to search library databases is to try using synonyms and related terms (option 2). This allows for a more comprehensive search, considering different variations of keywords and increasing the likelihood of finding relevant resources.

This assignment is for the students to review about using pointers in linked list in CH. The students need to complete the double_insert () function as shown below. template 〈class List_entry ⟩ Error_code List::double_insert(int position, const List_entry \&x1, const List_entry \& 2 \} \{ /**ost: If the List is not full and θ<= position ⇔=n, * where n is the number of entries in the List, * the function succeeds: * Any entry formerly at * position and all later entries have their * position numbers increased by 1 , and * x is inserted at position of the List. * Else: * The function fails with a diagnostic error code. * 3 Requirements: 1) Your implementation of double_insert must handle pointers directly. You are NOT allowed to implement double insert by invoking insert twice in its body. A grade of 0 will be assigned otherwise. On theother hand, you are allowed to use set_position in double_insert. 2) The error codes provided by double_insert should be similar to insert. For example, if position is out of range, range_err should be returned. 3) Once you finish your implementation of double_insert, you can uncomment lines 1113 in main.cpp to test-run your implementation. The program should print the letters a through h in alphabeticalorder from the list if your implementation is correct.
The assignment requires students to complete the "double_insert()" function in a linked list, focusing on direct pointer manipulation. The function should insert an element at a specified position in the list and return error codes consistent with the "insert" function. Once implemented, students can test their solution to ensure correct alphabetical ordering of letters from the list.
In this assignment, students are given the task of completing the "double_insert()" function in a linked list using pointers in C++. The function is responsible for inserting an element at a specified position in the list. However, there are specific requirements that need to be met.
Firstly, the implementation must directly handle pointers, meaning that students need to manipulate the pointers of the linked list nodes to perform the insertion, rather than using indirect methods such as invoking the "insert" function twice. This requirement aims to test the students' understanding and proficiency in working with pointers in a linked list.
Secondly, the error codes returned by the "double_insert()" function should be similar to those returned by the "insert" function. For example, if the specified position is out of range, the function should return a "range_err" error code. This requirement ensures consistency and standardization in error handling across different list operations.
Lastly, once the implementation of the "double_insert()" function is completed, students are encouraged to uncomment lines 11-13 in the "main.cpp" file. By doing so, they can test and validate their implementation. If the implementation is correct, the program should print the letters from the list in alphabetical order (letters 'a' through 'h').
By completing this assignment, students will gain hands-on experience in manipulating pointers in a linked list, implementing a specific insertion function, and ensuring proper error handling. These skills are fundamental in understanding and effectively working with data structures and algorithms.

Basics of Animation! When moving characters across the screen in computer animations, we don't explicitly assign every point they move to. Instead, we set "key frames" and use various techniques to automatically transition characters from one point to another. One of the most fundamental techniques is "linear interpolation" or "lerping". We can figure out where a character "should be" between two key frames if we know the starting point, ending point, and what percentage of the total time has passed. For this assignment, you will write a program that asks for this information and calculates the character's current X position using the linear interpolation formula shown below: Current X = Starting X + (Total Distance * (Current Frames Passed/Total Frames)) You will do two calculations - one for a 30 frames per second animation, and one for a 60 frames per second animation. Assume that Keyframe #2 is always to the right of Keyframe #1, and that both X coordinates are positive. The algorithm output is as shown below, with user input in bold. Follow the output format exactly. Save your source code in a file called Assignment2B (with a file extension of .cpp, .cs or java) Sample Output #1: [Lerping!] Enter the X coordinate for Keyframe #1:7 Enter the X coordinate for Keyframe #2: 19 How many frames have passed? 10 The character has to move 12 places in a second.

In conceptual level design, we will focus on capturing data requirement (entity types and their relationships) from the requirement. You don’t need to worry about the actual database table structures at this stage. You don’t need to identify primary key and foreign key, you need to identify unique values attributes and mark them with underline.
Consider following requirement to track information for a mini hospital, use EERD to capture the data requirement (entities, attributes, relationships). Identify entities with common attributes and show the inheritance relationships among them.
You can choose from Chen’s notation, crow’s foot notation, or UML.
The hospital tracks information for patients, physician, other personnel. The physician could be a patient as well.
All the patients have an ID, first name, last name, gender, phone, birthdate, admit date, billing address.
All the physicians have ID, first name, last name, gender, phone, birthdate, office number, title.
There are other personnel in the system, we need to track their first name, last name, gender, phone, birthdate.
A patient has one responsible physician. We only need to track the responsible physician in this system.
One physician can take care of many or no patients.
Some patients are outpatient who are treated and released, others are resident patients who stay in hospital for at least one night. The system stores checkback date for outpatients, and discharge date for resident patients.
All resident patients are assigned to a bed. A bed can be assigned to one resident patient.
A resident patient can occupy more than one bed (for family members).
A bed can be auto adjusted bed, manual adjusted bed, or just normal none-adjustable bed.
All beds have bed ID, max weight, room number. Auto adjusted beds have specifications like is the bed need to plug into power outlet, the type of the remote control. The manual adjust beds have specification like the location of the handle.
Please use design software
Please refer to the attached EERD diagram for the conceptual design capturing the data requirements, entities, attributes, and relationships for the mini hospital system.

if relation r and relation s are both 32 pages and round robin partitioned over 2 machines with 4 buffer pages each, what is the network cost (number of bytes sent over the network by any machine) for performing a parallel sort-merge join in the worst case? assume each page is 4kb.
In the worst case scenario of a parallel sort-merge join, with 32-page relations round-robin partitioned over 2 machines, the network cost is 131,072 bytes.
To calculate the network cost for performing a parallel sort-merge join, we need to consider the data transfer between the two machines. In the worst-case scenario, where none of the pages are already present in the buffer, each page will need to be transferred over the network.
Given:
Relation r and relation s are both 32 pages.Round-robin partitioning is used over 2 machines.Each machine has 4 buffer pages.Each page is 4KB in size.Since round-robin partitioning is used, each machine will hold half of the pages from both relations. Therefore, each machine will have 16 pages from relation r and 16 pages from relation s.
To perform the sort-merge join, the pages from relation r and s need to be sent between the machines. In the worst case, all pages need to be transferred.
Calculating the network cost for sending relation r pages:
Number of relation r pages = 16
Size of each page = 4KB = 4 x 1024 bytes
Network cost for relation r = Number of relation r pages * Size of each page
= 16 x (4 x 1024) bytes
Calculating the network cost for sending relation s pages:
Number of relation s pages = 16
Size of each page = 4KB = 4 x 1024 bytes
Network cost for relation s = Number of relation s pages x Size of each page
= 16 x (4 x 1024) bytes
Total network cost for the parallel sort-merge join (worst case) = Network cost for relation r + Network cost for relation s
Substituting the values:
Total network cost = (16 x (4 x 1024)) bytes + (16 x (4 x 1024)) bytes
Simplifying the calculation:
Total network cost = 65536 bytes + 65536 bytes
= 131072 bytes
Therefore, the network cost (number of bytes sent over the network by any machine) for performing a parallel sort-merge join in the worst case is 131,072 bytes.

The type of image results when the blue band is represented by blue, the green band is represented by green, and the red band is represented by red is a true color image. This type of image uses a combination of red, green, and blue (RGB) colors to create an image that closely resembles the natural colors of the subject.
True color images are created by assigning each pixel a value representing its color in RGB format. The red, green, and blue bands of the electromagnetic spectrum are sampled to provide this information. Each pixel has a combination of red, green, and blue colors, each color with a value between 0 and 255. This produces over 16 million possible color combinations for each pixel in the image.
A true color image requires a minimum of 24 bits per pixel, with 8 bits assigned to each color channel (red, green, and blue).
True color images are also known as RGB images and are widely used in photography, television, computer monitors, and other digital displays.

Name three different types of impairments of a data signal transmission, and state whether you think a digital signal or an analog signal is likely to be more adversely affected by each type of impairment
The three types of impairments of a data signal transmission are Attenuation, Distortion, and Noise. Digital signals are better at rejecting noise than analog signals.
Here is the information about each impairment and which signal is more likely to be adversely affected by them:
1. Attenuation:It occurs when the power of a signal is reduced during transmission. This can be due to the distance that the signal must travel or the nature of the transmission medium. An analog signal is more adversely affected by attenuation than a digital signal. This is because the digital signal is not dependent on the strength of the signal, it either reaches its destination or does not reach it.
2. Distortion:It occurs when the signal is altered in some way during transmission. This can be due to issues with the equipment or the transmission medium. Analog signals are more likely to be adversely affected by distortion than digital signals. This is because digital signals are less susceptible to distortion due to their binary nature.
3. Noise:It is unwanted electrical or electromagnetic energy that can interfere with the signal during transmission. It can be caused by a variety of sources, such as radio waves, electrical appliances, or other electronic equipment.
Both analog and digital signals can be adversely affected by noise. However, digital signals are better at rejecting noise than analog signals. This is because digital signals use techniques like error correction to reduce the impact of noise.

student dict = {'Alex': [60, 70, 80], 'Mark': [70, 80, 90], 'Luke': [90, 85, 95]}for name, scores in studentdict.items(): total = 0 for score in scores: total += score ave = total/len(scores) print("The average score of", name, "is", ave)Output: The average score of Alex is 70.0The average score of Mark is 80.0The average score of Luke is 90.0
In the given problem, we need to calculate the average score of each student. To solve this problem, we have to use the `studentdict` dictionary that is already defined as follows: studentdict = {'Alex': [60, 70, 80], 'Mark': [70, 80, 90], 'Luke': [90, 85, 95]}Now, we will iterate over the dictionary `studentdict` using `for` loop. For each `name` and `scores` in `studentdict.items()`, we will find the `total` score for that student and then we will calculate the `average` score of that student. At last, we will print the name of that student and its average score.Here is the solution:studentdict = {'Alex': [60, 70, 80], 'Mark': [70, 80, 90], 'Luke': [90, 85, 95]}# iterate over the dictionary for name, scores in studentdict.items(): # initialize the total score to 0 total = 0 # calculate the total score for that student for score in scores: total += score # calculate the average score of that student ave = total/len(scores) # print the name of that student and its average score print("The average score of",name, "is",ave)Output:
The average score of Alex is 70.0The average score of Mark is 80.0The average score of Luke is 90.0. In this problem, we have learned how to calculate the average score of each student by using the dictionary `studentdict`. We have also learned how to iterate over the dictionary using the `for` loop and how to calculate the average score of each student.

You are going to write a DoughnutTower game for a toddler! The aim of the game is to stack 5 doughnuts of the same colour (red/blue/green). The purpose of this DoughnutTower game assignment is to: - Use the provided MyArrayList class and add a method. - Write a StackAsMyArrayclass with the typical methods and two additional methods. - Write an implementation (test) class for the game. In order to check if a toddler has stacked the 5 doughnuts successfully, one needs to check if all the doughnuts in the tower are the same colour. - Find attached the MyArrayList class. Make the following addition in the MyArrayList class (Please use the given naming conventions): A generic version of this method: - public boolean checkUniform() The method should return true if all the doughnuts are identical. - Make sure you have an accessor for the instance variable called: public int getSize() - Write the StackAsMyArrayList class with: - Push(), Pop(), toString() - We are going to add 2 non-typical stack methods (just to make this game work) - public int getStackSize() which calls the getSize() method of the MyArrayList class - public boolean checkStackUniform() which calls the checkUniform() method of the MyArrayList class HINT: The toString() of the stack class calls the toString() of the MyArrayList class - Write an implementation (test) class for the game. Size: θ The tower is not full The the accompanying output as a guideline. Size:5 Correct? false The tower: [r,r,r] Size:3 The tower is not full The tower: [r,r,r,r,r] Size:5 Correct? true
To complete the programming assignment, you will need to perform the following tasks -
The steps and tasks to be executedUse the provided MyArrayList class and add a generic method called public boolean checkUniform(). This method should return true if all the doughnuts in the tower are identical.
Write the StackAsMyArrayList class with the following methods - push(), pop(), and toString(). The toString() method should call the toString() method of the MyArrayList class.
In the StackAsMyArrayList class, add two non-typical stack methods - public int getStackSize() which calls the getSize() method of the MyArrayList class, and public boolean checkStackUniform() which calls the checkUniform() method of the MyArrayList class.
Write an implementation (test) class for the game. This class should create instances of the StackAsMyArrayList class, perform operations such as pushing and popping doughnuts onto the stack, and check if the tower meets the criteria of having 5 doughnuts of the same color. The sample output provided in the description can serve as a guideline for the expected results.
