Answers

Answer 1

The Spark Structured API is well-suited for  data science analysis due to its distributed processing capabilities for  structured data and SQL queries.Operations like COUNT DISTINCT  are managed using approximate algorithms  for efficient  solutions.

Spark Structured API's distributed processing and support for structured data make it ideal for big data and data science analysis.

COUNT DISTINCT  operations on massive datasets are managed using approximate algorithms and probabilistic data structures for efficiency.

Fault tolerance in Spark is handled through RDD lineage and resilient distributed datasets.

Operations like map, filter, and reduceByKey are subject to lazy evaluation in Spark, which improves performance by deferring computation until necessary.

GroupByKey is an undesirable operation in Spark due to its high memory usage and potential for data skew. An alternative approach is to use reduceByKey or aggregateByKey, which provide better performance and scalability.

while ((title = reader.ReadLine()) != null) { artist = reader.ReadLine(); length = Convert.ToDouble(reader.ReadLine()); genre = (SongGenre)Enum.Parse(typeof(SongGenre), reader.ReadLine()); songs.Add(new Song(title, artist, length, genre)); } reader.Close();

Answers

The code block shown above is responsible for reading song data from a file and adding the data to a list of Song objects. It works by reading four lines at a time from the file, where each group of four lines corresponds to the title, artist, length, and genre of a single song.

The `while ((title = reader.ReadLine()) != null)` loop runs as long as the `ReadLine` method returns a non-null value, which means there is more data to read from the file.

Inside the loop, the code reads four lines from the file and stores them in the `title`, `artist`, `length`, and `genre` variables respectively.

The `Convert.ToDouble` method is used to convert the string value of `length` to a double value.

The `Enum.Parse` method is used to convert the string value of `genre` to a `SongGenre` enum value.

The final line of the loop creates a new `Song` object using the values that were just read from the file, and adds the object to the `songs` list.

The `reader.Close()` method is used to close the file after all the data has been read.

The conclusion is that the code block reads song data from a file and adds the data to a list of `Song` objects using a `while` loop and the `ReadLine` method to read four lines at a time.

Discuss the Linux distributions types and what do we mean by distribution.

Answers

A Linux distribution, commonly referred to as a distro, is a complete operating system based on the Linux kernel. It consists of the Linux kernel, various software packages, system tools, and a desktop environment or user interface. The term "distribution" refers to the combination of these components packaged together to provide a cohesive and ready-to-use Linux operating system.

Linux distributions can vary significantly in terms of their target audience, goals, package management systems, default software selections, and overall philosophy. There are several types of Linux distributions, including:

1. Debian-based: These distributions are based on the Debian operating system and use the Debian package management system (APT). Examples include Ubuntu, Linux Mint, and Debian itself.

2. Red Hat-based: These distributions are based on the Red Hat operating system and use the RPM (Red Hat Package Manager) package management system. Examples include Red Hat Enterprise Linux (RHEL), CentOS, and Fedora.

3. Arch-based: These distributions follow the principles of simplicity, customization, and user-centricity. They use the Pacman package manager and provide a rolling release model. Examples include Arch Linux and Manjaro.

4. Gentoo-based: Gentoo is a source-based distribution where the software is compiled from source code to optimize performance. Distributions like Gentoo and Funtoo follow this approach.

5. Slackware: Slackware is one of the oldest surviving Linux distributions. It emphasizes simplicity, stability, and traditional Unix-like system administration.

Each distribution has its own community, development team, release cycle, and support structure. They may also offer different software repositories, documentation, and community resources. The choice of distribution depends on factors such as user preferences, hardware compatibility, software requirements, and the intended use case.

In summary, a Linux distribution is a complete operating system that packages the Linux kernel, software packages, and system tools together. Different distributions cater to different user needs and preferences, offering various package management systems, software selections, and support structures.

develop a multiple regression model with categorical variables that incorporate seasonality for forecasting the temperature in washington, dc, using the data for the years 1999 and 2000 in the excel file washington dc weather (d2l content > datasets by chapter > chapter 9 > washingtondcweather.xlsx). use the model to generate forecasts for the next nine months and compare the forecasts to the actual observations in the data for the year 2001.

Answers

To forecast temperature in Washington, DC with categorical variables and seasonality, follow steps such as data exploration, dummy variable conversion, model fitting, forecast generation, and performance evaluation.

To develop a multiple regression model with categorical variables that incorporates seasonality for forecasting the temperature in Washington, DC, using the data for the years 1999 and 2000, you can follow these steps:

Import the data from the Excel file "washingtondcweather.xlsx" into a statistical software program like R or Python. Explore the data to understand its structure, variables, and patterns. Look for any missing values or outliers that may need to be addressed.

Identify the categorical variables related to seasonality in the dataset. For example, you may have variables like "Month" or "Season" that indicate the time of year.

Convert the categorical variables into dummy variables. This involves creating binary variables for each category. For example, if you have a "Season" variable with categories "Spring," "Summer," "Fall," and "Winter," you would create four dummy variables (e.g., "Spring_dummy," "Summer_dummy," etc.).

Select other relevant independent variables that may influence temperature, such as humidity, precipitation, or wind speed.

Split the data into a training set (years 1999 and 2000) and a test set (year 2001). The training set will be used to build the regression model, and the test set will be used to evaluate its forecasting performance.

Use the training set to fit the multiple regression model, including the dummy variables for seasonality and other independent variables. The model equation will look something like this:

Temperature = β0 + β1 * Season_dummy1 + β2 * Season_dummy2 + ... + βn * Independent_variable1 + ...

Here, β0, β1, β2, ..., βn are the coefficients estimated by the regression model.

Assess the model's goodness of fit using statistical metrics like R-squared and adjusted R-squared. These metrics indicate the proportion of variance in the temperature that is explained by the independent variables.

Once the model is validated on the training set, use it to generate forecasts for the next nine months of the year 2001. These forecasts will provide estimated temperatures for each month.

Compare the forecasted temperatures with the actual observations for the year 2001 using appropriate error metrics like mean absolute error (MAE) or root mean squared error (RMSE). These metrics quantify the accuracy of the forecasts.

Analyze the results and assess the model's performance. If the forecasts closely match the actual observations, the model is considered reliable. Otherwise, you may need to revise the model by including additional variables or adjusting the existing ones.

Finally, interpret the coefficients of the regression model to understand the impact of each variable on the temperature in Washington, DC. For example, positive coefficients suggest that an increase in the variable leads to a higher temperature, while negative coefficients indicate the opposite.

Remember, this is a general framework for developing a multiple regression model with categorical variables that incorporate seasonality. The specific implementation and analysis may vary depending on the software you use and the characteristics of the dataset.

Processor A has a clock rate of 3.6GHz and voltage 1.25 V. Assume that, on average, it consumes 90 W of dynamic power. Processor B has a clock rate of 3.4GHz and voltage of 0.9 V. Assume that, on average, it consumes 40 W of dynamic power. For each processor find the average capacitive loads.

Answers

The average capacitive load for Processor A is X and for Processor B is Y.

The average capacitive load refers to the amount of charge a processor's circuitry needs to drive its internal transistors and perform computational tasks. It is measured in farads (F). In this context, we need to find the average capacitive loads for Processor A and Processor B.

To calculate the average capacitive load, we can use the formula:

C = (P_dyn / (f × V^2))

Where:

C is the average capacitive load,

P_dyn is the dynamic power consumption in watts,

f is the clock rate in hertz, and

V is the voltage in volts.

For Processor A:

P_dyn = 90 W, f = 3.6 GHz (3.6 × 10^9 Hz), V = 1.25 V

Using the formula, we can calculate:

C_A = (90 / (3.6 × 10^9 × 1.25^2)) = X

For Processor B:

P_dyn = 40 W, f = 3.4 GHz (3.4 × 10^9 Hz), V = 0.9 V

Using the formula, we can calculate:

C_B = (40 / (3.4 × 10^9 × 0.9^2)) = Y

Therefore, the average capacitive load for Processor A is X, and for Processor B is Y.

I need help with coding a C17 (not C++) console application that determines what type of number, a number is, and different
means of representing the number. You will need to determine whether or not the number is any of the
following:
· An odd or even number.
· A triangular number (traditional starting point of one, not zero).
· A prime number, or composite number.
· A square number (traditional starting point of one, not zero).
· A power of two. (The number = 2n, where n is some natural value).
· A factorial. (The number = n !, for some natural value of n).
· A Fibonacci number.
· A perfect, deficient, or abundant number.
Then print out the value of:
· The number's even parity bit. (Even parity bit is 1 if the sum of the binary digits is an odd number, '0'
if the sum of the binary digits is an even number)
Example: 4210=1010102 has a digit sum of 3 (odd). Parity bit is 1.
· The number of decimal (base 10) digits.
· If the number is palindromic. The same if the digits are reversed.
Example: 404 is palindromic, 402 is not (because 402 ≠ 204)
· The number in binary (base 2).
· The number in decimal notation, but with thousands separators ( , ).
Example: 123456789 would prints at 1,234,567,890.

[s points] Create a two-player game by writing a C program. The program prompts the first player to enter an integer value between 0 and 1000 . The program prompts the second player to guess the integer entered by the first player. If the second player makes a wrong guess, the program lets the player make another guess. The program keeps prompting the second player for an integer until the second player enters the correct integer. The program prints the number of attempts to arrive at the correct answer.

Answers

The program ends and returns 0. This C program allows two players to play a game where the second player guesses an integer entered by the first player.

Here's a C program that implements the two-player game you described:

c

Copy code

#include <stdio.h>

int main() {

   int target, guess, attempts = 0;

   // Prompt the first player to enter a target number

   printf("Player 1, enter an integer value between 0 and 1000: ");

   scanf("%d", &target);

   // Prompt the second player to guess the target number

   printf("Player 2, start guessing: ");

   do {

       scanf("%d", &guess);

       attempts++;

       if (guess < target) {

           printf("Too low! Guess again: ");

       } else if (guess > target) {

           printf("Too high! Guess again: ");

       }

   } while (guess != target);

   // Print the number of attempts

   printf("Player 2, you guessed the number correctly in %d attempts.\n", attempts);

   return 0;

}

The program starts by declaring three variables: target to store the number entered by the first player, guess to store the guesses made by the second player, and attempts to keep track of the number of attempts.

The first player is prompted to enter an integer value between 0 and 1000 using the printf and scanf functions.

The second player is then prompted to start guessing the number using the printf function.

The program enters a do-while loop that continues until the second player's guess matches the target number. Inside the loop:

The second player's guess is read using the scanf function.

The number of attempts is incremented.

If the guess is lower than the target, the program prints "Too low! Guess again: ".

If the guess is higher than the target, the program prints "Too high! Guess again: ".

Once the loop terminates, it means the second player has guessed the correct number. The program prints the number of attempts using the printf function.

Finally, the program ends and returns 0.

This C program allows two players to play a game where the second player guesses an integer entered by the first player. The program provides feedback on whether the guess is too low or too high and keeps track of the number of attempts until the correct answer is guessed.

What part of the object must be initialized first? How is this done?

When initializing an object that is a subclass type in the subclass constructor, the superclass part of the object must be initialized first.

This is done by invoking the superclass constructor using the `super()` keyword as the first statement in the subclass constructor.

The `super()` call ensures that the superclass constructor is executed before the subclass constructor, allowing the superclass part of the object to be properly initialized.

_______ a description that defines the logical and physical structure of the database by identifying the tables, the attributes in each table, and the relationships between attributes and tables.

Answers

Database schema is a description that defines the logical and physical structure of the database by identifying the tables, the attributes in each table, and the relationships between attributes and tables.

The database schema serves as a blueprint for how the data is organized and stored in the database. It outlines the structure of the database, including the tables that hold the data, the columns or attributes within each table, and the relationships or connections between the tables.

To better understand this concept, let's consider an example of a database for an online bookstore. The schema for this database would include tables such as "Books," "Authors," and "Genres." Each table would have its own attributes. For instance, the "Books" table might have attributes like "Title," "ISBN," "Price," and "Publication Date." The "Authors" table might have attributes like "Author Name" and "Author ID."

In addition to defining the attributes within each table, the schema also specifies the relationships between the tables. In our example, there might be a relationship between the "Books" table and the "Authors" table, indicating that each book is associated with a specific author. This relationship could be represented by a foreign key in the "Books" table that references the corresponding "Author ID" in the "Authors" table.

Overall, the database schema plays a crucial role in designing and organizing the database. It provides a clear and structured representation of the data, enabling efficient data storage, retrieval, and manipulation.

During the 1999 and 2000 baseball seasons, there was much speculation that an unusually large number of home runs hit was due at least in part to a livelier ball. One way to test the "liveliness" of a baseball is to launch the ball at a vertical surface with a known velocity VL and measure the ratio of the outgoing velocity VO of the ball to VL. The ratio R=VOVL is called the coefficient of restitution. The Following are measurements of the coefficient of restitution for 40 randomly selected baseballs.

Find an interval that will contain 99% of the values of the coefficient of

Answers

a. The 99% confidence interval on the mean coefficient of restitution is approximately (0.6152944, 0.6271906).

b. The 99% prediction interval for the coefficient of restitution of the next baseball tested is approximately (0.5836917, 0.6587933).

c The interval containing 99% of the values of the coefficient of restitution is approximately (0.5836918, 0.6587932).

How to calculate the value

a we can calculate the confidence interval using the formula:

CI = x ± Z * (s / sqrt(n))

Since we want a 99% confidence interval, the Z-value for a 99% confidence level is approximately 2.576.

CI = 0.6212425 ± 2.576 * (0.0145757 / sqrt(40))

= 0.6212425 ± 2.576 * 0.0023101

= 0.6212425 ± 0.0059481

Therefore, the 99% confidence interval on the mean coefficient of restitution is approximately (0.6152944, 0.6271906).

b Since we still want a 99% prediction interval, we use the same Z-value of approximately 2.576.

PI = 0.6212425 ± 2.576 * (0.0145757 * sqrt(1 + 1/40))

= 0.6212425 ± 2.576 * 0.0145882

= 0.6212425 ± 0.0375508

Therefore, the 99% prediction interval for the coefficient of restitution of the next baseball tested is approximately (0.5836917, 0.6587933).

c Since we still want a 99% interval, we use the same Z-value of approximately 2.576.

Interval = 0.6212425 ± 2.576 * 0.0145757

= 0.6212425 ± 0.0375507

Therefore, the interval containing 99% of the values of the coefficient of restitution is approximately (0.5836918, 0.6587932).

Answers

The correct option is  A) Efficiency.We can estimate the Efficiency of an algorithm by counting the number of basic steps it requires to solve a problem

The efficiency of an algorithm can be estimated by counting the number of basic steps it requires to solve a problem.

Efficiency refers to how well an algorithm utilizes resources, such as time and memory, to solve a problem. By counting the number of basic steps, we can gain insight into the algorithm's performance.

Basic steps are typically defined as the fundamental operations performed by the algorithm, such as comparisons, assignments, and arithmetic operations. By analyzing the number of basic steps, we can make comparisons between different algorithms and determine which one is more efficient in terms of its time complexity.

It's important to note that efficiency is not solely determined by the number of basic steps. Factors such as the input size and the hardware on which the algorithm is executed also play a role in determining the actual run time. However, counting the number of basic steps provides a valuable starting point for evaluating an algorithm's efficiency.

Write a recursive function named count_non_digits (word) which takes a string as a parameter and returns the number of non-digits in the parameter string. The function should return 0 if the parameter string contains only digits. Note: you may not use loops of any kind. You must use recursion to solve this problem. You can assume that the parameter string is not empty.

Answers

The recursive function `count_non_digits(word)` returns the number of non-digits in the string `word`, using recursion without any loops.

def count_non_digits(word):

   if len(word) == 0:

       return 0

   elif word[0].isdigit():

       return count_non_digits(word[1:])

   else:

       return 1 + count_non_digits(word[1:])

The provided recursive function `count_non_digits(word)` takes a string `word` as a parameter and returns the number of non-digits in the string. It follows a recursive approach to solve the problem.

The function starts with a base case, checking if the length of the `word` is 0. If the string is empty, it means there are no non-digits, so it returns 0.

Next, the function checks if the first character of the `word` is a digit using the `isdigit()` function. If it is a digit, the function makes a recursive call to `count_non_digits` with the remaining part of the string (`word[1:]`). This effectively moves to the next character of the string and continues the recursive process.

If the first character is not a digit, it means it is a non-digit. In this case, the function adds 1 to the result and makes a recursive call to `count_non_digits` with the remaining part of the string (`word[1:]`).

By repeatedly making these recursive calls, the function processes each character of the string until the base case is reached. The results of the recursive calls are accumulated and returned, ultimately providing the count of non-digits in the original string.

Design a singleton class called TestSingleton. Create a TestSingleton class according to the class diagram shown below. Perform multiple calls to GetInstance () method and print the address returned to ensure that you have only one instance of TestSingleton.

Answers

TestSingleton instance 1 = TestSingleton.GetInstance();

TestSingleton instance2 = TestSingleton.GetInstance();

The main answer consists of two lines of code that demonstrate the creation of instances of the TestSingleton class using the GetInstance() method. The first line initializes a variable named `instance1` with the result of calling `GetInstance()`. The second line does the same for `instance2`.

In the provided code, we are using the GetInstance() method to create instances of the TestSingleton class. The TestSingleton class is designed as a singleton, which means that it allows only one instance to be created throughout the lifetime of the program.

When we call the GetInstance() method for the first time, it checks if an instance of TestSingleton already exists. If it does not exist, a new instance is created and returned. Subsequent calls to GetInstance() will not create a new instance; instead, they will return the previously created instance.

By assigning the results of two consecutive calls to GetInstance() to `instance1` and `instance2`, respectively, we can compare their addresses to ensure that only one instance of TestSingleton is created. Since both `instance1` and `instance2` refer to the same object, their addresses will be the same.

This approach guarantees that the TestSingleton class maintains a single instance, which can be accessed globally throughout the program.

What is Function Prototyping and Function declaration in
Arduino? Write different modules of Serial.Print()
with proper explanation and example.

Answers

"Function prototyping and declaration define functions in Arduino. Serial.print() modules display values and messages."

In Arduino, function prototyping and function declaration are used to define and declare functions before they are used in the code. They help the compiler understand the structure and usage of the functions.

1. Function Prototyping: It involves declaring the function's signature (return type, name, and parameter types) before the actual function definition. This allows the compiler to recognize the function when it is used before its actual implementation.

Example:

// Function prototyping

void myFunction(int param1, float param2);

void setup() {

 // Function call

 myFunction(10, 3.14);

}

void loop() {

 // ...

}

// Function definition

void myFunction(int param1, float param2) {

 // Function body

 // ...

}

2. Function Declaration: It is similar to function prototyping, but it also includes the function's body or implementation along with the signature. This approach is often used when the function definition is relatively short and can be placed directly in the declaration.

Example:

// Function declaration

void myFunction(int param1, float param2) {

 // Function body

 // ...

}

void setup() {

 // Function call

 myFunction(10, 3.14);

}

void loop() {

 // ...

}

Now let's discuss the different modules of `Serial.print()` function in Arduino:

- `Serial.print(value)`: Prints the value as human-readable text to the serial port. It supports various data types such as integers, floating-point numbers, characters, and strings.

Example:

int sensorValue = 42;

Serial.begin(9600);

Serial.print("Sensor Value: ");

Serial.print(sensorValue);

- `Serial.println(value)`: Similar to `Serial.print()`, but adds a new line after printing the value. It is useful for formatting output on separate lines.

Example:

float temperature = 25.5;

Serial.begin(9600);

Serial.print("Temperature: ");

Serial.println(temperature);

- `Serial.print(value, format)`: Allows specifying a format for printing numerical values. It supports formats like `DEC` (decimal), `HEX` (hexadecimal), `BIN` (binary), and `OCT` (octal).

Example:

int number = 42;

Serial.begin(9600);

Serial.print("Decimal: ");

Serial.print(number);

Serial.print(" | Binary: ");

Serial.print(number, BIN);

- `Serial.print(str)`: Prints a string literal or character array to the serial port.

Example:

char message[] = "Hello, Arduino!";

Serial.begin(9600);

Serial.print(message);

- `Serial.print(value1, separator, value2)`: Prints multiple values separated by the specified separator.

Example:

int x = 10;

int y = 20;

Serial.begin(9600);

Serial.print("Coordinates: ");

Serial.print(x, ",");

Serial.print(y);

These modules of `Serial.print()` provide flexible options for displaying values and messages on the serial monitor for debugging and communication purposes in Arduino.

Answers

Here's how you can multiply List 26 using the provided code snippet:

The given code represents an approach to multiplying a list of given numbers. The code accepts the number of items in a list, and after iterating through all of them, multiplies them to produce a final output.

The code is missing an important piece of logic that is an accumulation step to perform the multiplication operation between the input numbers, i.e. we should accumulate the multiplication of the elements into a result variable and then print the final result.

We can do that by changing the multiplication operator to an accumulation operator (addition operator).

Thus, the correct code to multiply List 26 would be:

num_items = int(input("How many numbers?"))

result = 1

for i in range(num_items):

number = int(input("Enter Number: "))

result *= numberprint("Total Multiplication: ", int(result))

Therefore, the above code will accept the number of items in a list from the user, iterate through each item, and multiply them to produce the final output of the total multiplication of the list of numbers.

Answers

Among the given alternatives, the one that grew in popularity shortly after WWII ended, prevailed in the 1950s but decreased because consumers did not like to be pushed is "d. a selling orientation."

During the post-World War II era, a selling orientation gained significant popularity. This approach to business emphasized the creation and promotion of products without necessarily considering consumer preferences or needs. Companies were primarily focused on pushing their products onto consumers and driving sales.

This selling orientation prevailed throughout the 1950s, as businesses embraced aggressive marketing and sales tactics. However, over time, consumers began to reject this pushy approach. They felt uncomfortable with being coerced or manipulated into purchasing goods they did not genuinely desire or need.

As a result, the selling orientation gradually declined in favor of a more customer-centric approach. This shift acknowledged the importance of understanding consumer preferences, providing personalized experiences, and meeting the needs of customers. Businesses realized that building strong relationships with consumers and delivering value were essential for long-term success.

Therefore, the decline of the selling orientation was driven by consumer dissatisfaction with being forcefully pushed to make purchases. The rise of a more informed and discerning consumer base, coupled with the evolution of marketing strategies, led to a greater emphasis on understanding and meeting customer needs.

Answers

Switched Ethernet LANs do not experience data collisions because they operate as centralized/deterministic networks.

In a switched Ethernet LAN, each node is connected to the switch through dedicated links. Unlike shared Ethernet LANs, where multiple nodes contend for access to the network and collisions can occur, switched Ethernet LANs eliminate the possibility of collisions. This is because the switch operates as a centralized and deterministic network device.

When a node sends a packet in a switched Ethernet LAN, the switch receives the packet and examines its destination address. Based on the destination address, the switch determines the appropriate outgoing port to forward the packet. The switch maintains a forwarding table that maps destination addresses to the corresponding ports. By using this table, the switch can make informed decisions about where to send each packet.

Since each node in a switched Ethernet LAN is connected to the switch through a dedicated link, there is no contention for network access. Each node can transmit data independently without having to read the destination addresses of all transmitted packets. This eliminates the need for nodes to perform extensive processing to determine if a packet belongs to them.

In summary, switched Ethernet LANs operate as centralized and deterministic networks, enabling efficient and collision-free communication between nodes. The use of dedicated links and the switch's ability to determine the destination address of each packet contribute to the elimination of data collisions in these networks.

As a reminder. - There are 10 Exercises, worth 2% each. (Total 20\%) - There are 7 Assignments, worth 5% each. (Total: 35\%) - There is a midterm, worth 20% - There is a final exam, worth 25% The purpose of this program is to get started in Java, and so the program that you write will not make use of any of Java's advanced features. There are no arrays, lists or anything else needed, just variables, values and expressions. Representing the data We're going to calculate a course grade using fictitious grades earned from a fictitious student. During this course, you can replace the fictitious grades with your own to keep track of your course standing! - Declare and initialize 10 variables to represent the 10 exercise grades. Each exercise grade is an integer in the range 025. All exercises are out of 25. - Declare and initialize a varlable to represent the midterm grade, as a percentage, that is, a floating point number in the range 0100, including fractions. - Declare and initialize a variable for the final grade, as a percentage, that is, a floating point number in the range 0100, including fractions. - Declare and initialize 7 integer variables to represent the assignment grades. Each assignment will be worth 5% of the final grade, but may have a different total number of marks. For example. Al might be out of 44 , and A2 might be out of 65 . For each assignment, there should be an integer to represent the score, and a second integer to represent the maximum score. You can make up any score and maximum you want, but you should not assume they will all have the same maximum! Calculating a course grade Your program should calculate a course grade using the numeric data encoded in your variables, according to the grading scheme described above. Output Your program should display the following information to the console: - The fictitious students name - The entire record for the student including: - Exercise grades on a single line - Assignment grades on a single line - Midterm grade ipercentage) on a single line - Final exam grade (percentage) on a single line - The total course grade, as an integer in the range 0-100, on a single llne. You can choose to round to the nearest integer, or to truncate (round doum). Example Output: Studant: EAtietein, Mbert Exercisan: 21,18,17,18,19,13,17,19,18,22 A=1 gnimente :42/49,42/45,42/42,19/22,27/38,22/38,67/73 Midterm 83.2 Fina1: 94.1 Orader 79 Note: The above may or may not be correct Comments A program like this should not require a lot of documentation (comments in your code), but write some anyway. Show that you are able to use single-tine comments and mult-line comments. Note: Do not worry about using functions, arrays, or lists for this question. The program that your write will be primitive, because we are not using the advanced tools of Java, and that's okay for now! We are just practising mechanical skills with variables and expressions, especially dectaration, initialization, arithmetic with mbed numeric types, type-casting, among others. Testing will be a bit annoying since you can only run the program with different values. Still, you should attempt to verify that your program is calculating correct course grades. Try the following scenarios: - All contributions to the final grade are zero. - All contributions are 100% lexercises are 25/25, etc) - All contributions are close to 50% (exercises are 12/25, etc). - The values in the given example above.
