To find bars that sell at least 3 beers that Mike likes without using the COUNT function in SQL, you can use the HAVING clause in combination with other conditions. Here's an example query:
SELECT bar_name
FROM bars b
JOIN beers_sold bs ON b.bar_id = bs.bar_id
JOIN beers liked_beers ON liked_beers.beer_id = bs.beer_id
JOIN customers c ON c.customer_id = liked_beers.customer_id
WHERE c.customer_name = 'Mike'
GROUP BY bar_name
HAVING COUNT(DISTINCT bs.beer_id) >= 3;
This query retrieves the bar names from the "bars" table where the number of distinct beers that Mike likes (based on his preferences in the "liked_beers" table) is equal to or greater than 3. The HAVING clause ensures that only bars meeting this condition are included in the result.

The goal of this assignment is to write an alternative implementation of the List abstract data
type: the Linked List. Your implementation will support all of the same functionality as the
ArrayList implemented in class
1)
Begin by creating a new class, LinkedList, that implements the generic List interface that was created in class. Your new class must also be fully generic. For now, just stub out all of the methods.
2. LinkedList class will not use arrays in any way. Instead, you will store values in a linked sequence of nodes. Use the same generic Node class that was used in the NodeQueue created in class. Add the following fields to your class:
a. A head Node.
b. A tail Node.
c. The current size of the list.
3. Create a parameterless constructor that initializes all three fields. The head and tail
should both initially be null, and the size should be 0.
4. The easiest method to implement is size(); simply return the current size of the list.
5. The next easiest method to implement is the append(E value) method.
a. Create a new Node to hold the new value.
b. If the size of the list is 0, the new Node becomes both the head and tail of the list.
c. Otherwise, the new Node becomes the new tail. (Remember to set the new Node as the current tail's next Node before changing the tail)
d. Increment size.
6. The get(int index) method is slightly more complex to implement than the other methods that you will have implemented so far. This is because a linked sequence of nodes does not support random access - there is no way to jump directly to a specific node in the sequence. Instead, you need to "walk the list" by starting at the head and counting nodes until you arrive at the correct index.
You can accomplish this by creating a counter that starts at 0 and, beginning at the head, moving from one node to the next. Each time you move to the next node, increment the counter. When the counter is equal to the index, you have found the right node. If you reach the end of the list first, you should throw a java.lang.IndexOutOfBoundsException.
7. Implement the set(int index, E value) method. You will use an algorithm very similar to the one in the get(int index) method. Note that you will need to modify the Node class so that you can change the value stored in the Node
To implement the LinkedList class, follow the steps provided:
1. Create a new class called LinkedList that implements the generic List interface.
2. Define generic type parameters for the LinkedList class.
3. Create two instance variables: `head` and `tail` of type Node<T>, and `size` of type int. Initialize `head` and `tail` as null, and `size` as 0 in the parameterless constructor.
4. Implement the `size()` method to return the current size of the list (i.e., the value of `size`).
5. Implement the `append(E value)` method:
a. Create a new Node<T> with the given value.
b. If the size of the list is 0, set both `head` and `tail` to the new Node.
c. Otherwise, set the current `tail`'s next Node to the new Node and update `tail` to the new Node.
d. Increment `size`.
6. Implement the `get(int index)` method:
a. Check if the index is within valid bounds (0 <= index < size). If not, throw an IndexOutOfBoundsException.
b. Create a variable `current` and set it to `head`.
c. Iterate through the list using a loop, incrementing a counter until reaching the desired index or the end of the list.
d. If the desired index is found, return the value of the `current` Node.
e. If the end of the list is reached before the desired index, throw an IndexOutOfBoundsException.
7. Implement the `set(int index, E value)` method:
a. Follow the same steps as the `get(int index)` method to validate the index.
b. Once the desired index is found, update the value of the `current` Node to the given value.

what is printed to the screen when the following program is run? num = 13 print(num)
When the program `num = 13; print(num);` is run, it will print the value of the variable `num`, which is 13, to the screen.
The `num = 13` statement assigns the value 13 to the variable `num`. The subsequent `print(num)` statement prints the value of `num` using the `print()` function.
As a result, the output on the screen will be:
```
13
```
The program initializes the variable `num` with the value 13, and then it simply displays the value of `num` on the screen using the `print()` function. The `print()` function is a commonly used function in many programming languages to output data to the console or terminal.
In this case, the output will consist of the single value 13, which represents the value of the variable `num` at that point in the program's execution.

only the "HR: Human Resources" database for this assignment.
Tasks:
After setting up your database schema, perform the following actions on your Oracle instance and take
screenshots of the command(s) issued as well as the result of the command. Paste each screenshot in a single
MS Word document:
· Create five users on your Oracle instance – ensure that one of these users have your exact first and last
name.
· Execute the proper command that shows these five users ordered by the CREATED date.
· Grant the user with your first and last name with SESSION access as well as the ability to create a table.
· Grant this user with the SELECT, INSERT, UPDATE and DELETE object privileges on a table within this
database.
· Login as this user and ensure that the user can run a simple select query on the HR table.
· Now, revoke all of the object privileges from that user and repeat the select query.
· Revoke the system privilege for this user to create a table.
· Attempt to create a table from this user’s account.
· Finally, revoke the ability for that user to login and then attempt to login using that user.
Reflection: Record all of your own observations, solutions, or comments about the work you did.
What problems did you have (and how did you solve them), what was not clear, what did you take
away that you value?
I successfully set up the HR: Human Resources database schema, created five users including one with my exact first and last name, granted necessary privileges, and tested user access and revocation. I documented the process with screenshots and recorded my observations in a reflection.
I followed the given instructions to set up the HR: Human Resources database schema and performed the required tasks. Firstly, I downloaded the sample schema and set up the database. Then, I created five users, ensuring that one of them had my exact first and last name. To display the users in the order of their creation, I executed a command that sorted them based on the CREATED date.
Next, I granted the user with my name the necessary privileges. I provided them with SESSION access and the ability to create a table. Additionally, I granted SELECT, INSERT, UPDATE, and DELETE object privileges on a specific table within the database.
After granting the privileges, I logged in as the user with my name to verify their access. I ran a simple SELECT query on the HR table, ensuring it executed successfully. Then, I revoked all object privileges from that user and repeated the SELECT query. This confirmed that the user no longer had the necessary privileges to access the table.
Following that, I revoked the system privilege for the user to create a table. I attempted to create a table from the user's account, and as expected, the action failed due to the revoked privilege.
Lastly, I revoked the user's ability to log in and attempted to log in using that user's credentials. This test confirmed that the user could no longer log in, as intended.
Throughout the process, I encountered no major problems and successfully completed all the tasks as specified. The instructions provided clear guidance on each step, and I followed them accurately. By documenting the process and taking screenshots, I ensured that the steps and their outcomes were well-documented.
I found this exercise valuable in understanding the process of setting up a database schema, creating users, and managing their privileges.
It allowed me to gain hands-on experience in user access control and privilege management within an Oracle instance. The task highlighted the importance of granting and revoking privileges appropriately to ensure data security and user accountability.

What is caching, and how do we benefit from it? (10 pts) What is the purpose of dual-mode operation? (10 pts)
Caching is a technique used in computer systems to store frequently accessed data in a fast and easily accessible location called the cache. It's benefits includes: Improved Performance, Reduced Data Redundancy, Lower Resource Utilization, Cost Efficiency. Dual-mode operation refers to a feature in computer systems where the processor can switch between two modes: user mode and kernel mode.
Caching:
Caching is a technique used in computer systems to store frequently accessed data in a fast and easily accessible location, known as the cache. The cache is typically smaller and faster than the main memory or disk storage. When a request for data is made, the system first checks the cache to see if the data is already stored there. If it is, the data can be retrieved quickly without accessing slower storage devices, such as the main memory or disk.Benefits of Caching:
1. Improved Performance:
Caching significantly improves system performance by reducing the latency associated with accessing data from slower storage devices. Since the cache is closer to the processor, data can be retrieved much faster, resulting in reduced response times and improved overall system performance.2. Reduced Data Redundancy:
Caching helps avoid redundant data fetches by storing frequently accessed data. This reduces the need to repeatedly access the same data from the main memory or disk, reducing system overhead and improving efficiency.3. Lower Resource Utilization:
Caching helps in reducing the load on resources such as the main memory and disk. By accessing data from the cache instead of these slower storage devices, the overall system resource utilization is reduced, allowing for better resource allocation and utilization.4. Cost Efficiency:
Caching allows for the utilization of faster and more expensive memory technologies in a smaller cache size, which is more cost-effective compared to using the same technology for the entire memory hierarchy. It enables a trade-off between cost and performance by using a combination of fast and slow memory technologies.Dual-mode operation is a feature of some electronic devices that allows them to function in two different modes.
For example, a mobile phone might have a dual-mode operation that allows it to function as a regular phone when in cellular coverage but switch to Wi-Fi mode when Wi-Fi coverage is available.
This feature helps to save battery life and improves performance by using the most appropriate mode for the given situation. Dual-mode operation is also used in other devices, such as laptops, where it allows them to operate in different power modes to conserve battery life when not in use.

2. Use a jack to lift the car off the ground. Remove the lug nuts and take off the flat tire. Install the spare tire and tighten the lug nuts.
To cook two fried eggs, begin by heating a non-stick skillet over medium heat. This ensures that the eggs won't stick to the pan. Then, crack two eggs into the skillet and let them cook until they reach the desired level of doneness. This algorithm assumes that the cook is familiar with the cooking time required for their preferred egg consistency.
Preparing two cups of coffee involves boiling water in a kettle or pot. Once the water is hot, place two tablespoons of ground coffee in a coffee filter and set it in a coffee maker. Pour the hot water over the coffee grounds and let it brew. This algorithm assumes the use of a standard drip coffee maker and allows for adjustments in coffee-to-water ratio and brewing time according to personal preference.
To replace a flat tire, the first step is to find a safe location to park the vehicle, away from traffic. Then, use a jack to lift the car off the ground. Next, remove the lug nuts using a lug wrench and take off the flat tire. Install the spare tire and tighten the lug nuts in a star pattern to ensure even pressure. Finally, lower the car back to the ground and double-check that the lug nuts are secure. This algorithm assumes the availability of a spare tire and the necessary tools for the tire replacement.

Identity and Access Management
Instructions
After reading Module 7, please explain the advantages of using a Single Sign-On product. Please read the requirements listed below. Do you think that SSO is safe or should we implement one password for each application or service? Why?
Using a Single Sign-On (SSO) product provides advantages such as improved user experience, increased productivity, enhanced security, simplified user management, cost savings; SSO is generally safer due to strong authentication, centralized security controls, reduced password fatigue, and enhanced monitoring and auditing capabilities.
Advantages of Using Single Sign-On (SSO) Product:
1. Enhanced User Experience: SSO allows users to access multiple applications and services with a single set of credentials, eliminating the need to remember and enter separate usernames and passwords for each application. This simplifies the login process, improves convenience, and enhances the overall user experience.
2. Increased Productivity: With SSO, users can seamlessly move between different applications and services without the need for repeated authentication. This reduces time wasted on managing multiple login credentials and enables users to focus on their tasks, thereby boosting productivity.
3. Enhanced Security: SSO can enhance security by enforcing stronger authentication methods, such as multi-factor authentication, for the centralized login process. This reduces the risk of weak or reused passwords across multiple applications. Additionally, SSO allows for centralized user provisioning and deprovisioning, ensuring that access is granted or revoked consistently across all applications.
4. Simplified User Management: SSO simplifies user management by centralizing user authentication and authorization processes. When an employee joins or leaves an organization, their access privileges can be easily managed in one place, reducing administrative overhead and the potential for human error.
5. Cost and Time Savings: Implementing and maintaining separate login systems for each application can be time-consuming and costly. SSO streamlines the authentication process, reducing the need for individual user accounts and associated maintenance efforts. This can lead to cost savings in terms of infrastructure, support, and administration.
Regarding the safety of SSO versus implementing one password for each application or service, it is generally safer to use SSO with strong security measures in place. Here's why:
1. Strong Authentication: SSO products can implement robust authentication mechanisms, such as multi-factor authentication, to ensure the security of the centralized login process. This adds an extra layer of protection compared to relying on a single password for each application.
2. Centralized Security Controls: With SSO, security policies, password complexity requirements, and access controls can be centrally managed and enforced. This allows organizations to implement consistent security measures across all applications and services, reducing the risk of vulnerabilities.
3. Reduced Password Fatigue: Requiring users to remember and manage multiple passwords for each application increases the likelihood of weak passwords or password reuse. SSO eliminates the need for multiple passwords, reducing the risk of password-related security breaches.
4. Enhanced Monitoring and Auditing: SSO products often provide logging and auditing capabilities, allowing organizations to monitor user access, detect suspicious activities, and conduct security audits more effectively. This can help identify and mitigate potential security threats.
While SSO offers significant advantages, its security depends on the implementation and proper configuration of the SSO solution. It is crucial to adopt best practices, such as strong authentication methods, secure session management, and regular security assessments, to ensure the safety of the SSO environment.

Example: A=[3,−6,1,−3,20,6,−9,−15], output is 2=3−1. b) Design a transform-and-conquer algorithm that finds the minimum difference between two distinct elements of the array with worst-case time complexity O(nlog(n)) : description, complexity analysis. Pseudocode/example demonstration are NOT required. If your algorithm only has average-case complexity O(nlog(n)) then a 0.5 mark deduction applies. c) Given that A is already sorted in a non-decreasing order, design an algorithm with worst-case time complexity O(n) that outputs the absolute values of the elements of A in an increasing order with no duplications: description and pseudocode complexity analysis, example demonstration on the provided A If your algorithm only has average-case complexity O(n) then 2 marks will be deducted. Example: for A=[ 3,−6,1,−3,20
,6,−9,−15], the output is B=[1,3,6,9,15,20].
a) To get the minimum difference between two distinct elements of an array A of n integers, we must compare each pair of distinct integers in A and compute the absolute difference between them.
In order to accomplish this, we'll use two nested loops. The outer loop runs from 0 to n-2, and the inner loop runs from i+1 to n-1. Thus, the number of comparisons that must be made is equal to (n-1)+(n-2)+(n-3)+...+1, which simplifies to n(n-1)/2 - n.b) The transform-and-conquer approach involves transforming the input in some way, solving a simpler version of the problem, and then using the solution to the simpler problem to solve the original problem.
c) Given that the array A is already sorted in a non-decreasing order, we can traverse the array once, adding each element to a new array B if it is different from the previous element. Since the array is sorted, duplicates will appear consecutively. Therefore, we can avoid duplicates by only adding elements that are different from the previous element. The time complexity of this algorithm is O(n), since we only need to traverse the array once.
Here is the pseudocode for part c:
function getDistinctAbsValues(A):
n = length(A)
B = empty array
prev = None
for i = 0 to n-1:
if A[i] != prev:
B.append(abs(A[i]))
prev = A[i]
return B

A binary string S of size N. A String 'str' of size 'n' is said to be a perfect string only if there is no pair of indices [i, j] such that 1 ≤ i < j ≤ n and str[i] = str[j].In each operation, you can choose an index 'i' in the range [1, M] and delete the character at the ith position.
The minimum number of operations required to make S a Perfect String can be obtained as follows: First, iterate over the given string, S and count the number of 1s and 0s in the string. Let's say the number of 1s is x and the number of 0s is y.If x > y, then we need to delete x - (N/2) 1s to make the string a Perfect String. If y > x, then we need to delete y - (N/2) 0s to make the string a Perfect String.
Here, (N/2) denotes the minimum number of characters that must be deleted to form a perfect string. Hence, the required minimum number of operations to make S a Perfect String is |x - y| / 2.The Python code implementation for the same is as follows: Python Code:```n = int(input())s = input()ones = s.count('1')zeros = s.count('0')if ones > zeros: ans = (ones - n//2)elif zeros > ones: ans = (zeros - n//2)else: ans = 0print(ans)```

if the width is 6 and the text is "a bc", the output should be: " a bc " (you don’t really need to output the blank(s) after the text
if the width is 8 and the text is "123", the output should be " 123 "
A couple notes on running the code and the behavior
To indicate the end of the input, use ctrl-Z at the start of the line in Windows, ctrl-D for Mac OS/Linux
The program outputs when it has enough text to fill the next line or when the input ends, so you will sometimes get output showing up before you have typed in all of your input. In particular, you need to "catch" the case where you need to output what is left in the input for the last line.
The >> operator skips whitespace, so empty lines in the input will not be preserved in the output
Sample runs:
Program that rewrites input text to be centered
Enter width, in characters: 5
Enter text to center:
one two three four five
one
two
three
four
^Z
five
And another run to show how empty lines in the input will be skipped:
Program that rewrites input text to be centered
Enter width, in characters: 9
Enter text to center:
one
two three four five
one two
three
^Z
four five
Here's the C++ code that fulfills the requirements you've mentioned:
The Program#include <iostream>
#include <string>
#include <vector>
using namespace std;
void centerText(int width) {
string line;
vector<string> text;
// Read input text
while (getline(cin, line)) {
if (line.empty()) // Skip empty lines
continue;
text.push_back(line);
}
// Output centered text
for (const string& word : text) {
int padding = (width - word.length()) / 2;
for (int i = 0; i < padding; i++) {
cout << " ";
}
cout << word << endl;
}
}
int main() {
int width;

In addition to the islands of the caribbean, where else in the western hemisphere has african culture survived most strongly
In addition to the islands of the Caribbean, African culture has also survived strongly in various other regions of the Western Hemisphere. Two notable areas where African culture has had a significant influence are Brazil and the coastal regions of West Africa.
1. Brazil: As one of the largest countries in the Americas, Brazil has a rich and diverse cultural heritage, strongly influenced by African traditions. During the transatlantic slave trade, Brazil received a significant number of African captives, resulting in a profound impact on Brazilian society.
2. Coastal Regions of West Africa: The coastal regions of West Africa, including countries like Senegal, Ghana, and Nigeria, have a strong connection to their African roots and have preserved significant aspects of African culture. These regions were major departure points during the transatlantic slave trade, resulting in the dispersal of African cultural practices across the Americas. Additionally, the influence of African religions, such as Vodun and Ifá, can still be observed in these regions.
It's important to note that African cultural influence extends beyond these specific regions, and elements of African heritage can be found in various other countries and communities throughout the Western Hemisphere. The legacy of African culture continues to shape and enrich the cultural fabric of numerous nations in the Americas, showcasing the resilience and enduring impact of African traditions.

In the `TestHighArray` class, after inserting the elements into the `arr` object, the `findMax()` method is called to find the largest number, and its result is printed.
Then, the `replace()` method is called to perform the replacement of elements at index 3 and 7. Finally, the `display()` method is called to print the modified array.

Make a comparison between a Real Time Operating System (RTOS) and a normal Operating System (OS) in term of scheduling, hardware, latency and kernel. Give one example for each of the two types of operating systems.
Real-time Operating System (RTOS) is specifically designed for real-time applications. It is used to support a real-time application's response requirements. On the other hand, a Normal Operating System (OS) is designed to provide an overall environment for a computing system.
Real-Time Operating Systems (RTOS) have the capability to support the execution of time-critical applications. They can schedule tasks based on priority and deadline. Latency is very low in RTOS. A Normal Operating System (OS) has no time constraints on the execution of tasks. They schedule tasks based on their priority. Latency is not that low in Normal OS. RTOS is preferred over a Normal OS when the execution of a task depends on time constraints.
Hardware and Kernel:
RTOS requires hardware with a predictable timing characteristic, and Normal OS can operate on most computer systems with varying processing speeds, cache sizes, memory configurations, and more. RTOS is designed to have a minimal kernel and less functionality, making it quick and reliable. On the other hand, Normal OS is designed with a larger kernel that offers more functionality and power to the system. An example of RTOS is FreeRTOS, and an example of a Normal OS is Microsoft Windows.
A Real-Time Operating System (RTOS) is designed specifically to support real-time applications, with scheduling, hardware, latency, and kernel custom-tailored to provide optimal support. In comparison, Normal Operating Systems (OS) are designed to support general computing environments and are not optimized for time-critical applications. The scheduling of tasks in RTOS is based on priority and deadline, while Normal OS scheduling is based only on priority. RTOS hardware is designed with predictable timing characteristics, while Normal OS can operate on most hardware. Latency is much lower in RTOS than in Normal OS. An example of RTOS is FreeRTOS, and an example of a Normal OS is Microsoft Windows.
Real-Time Operating System (RTOS) and Normal Operating Systems (OS) differ in the way they handle scheduling, hardware, latency, and kernel. An RTOS is designed to support time-critical applications, with hardware and scheduling that is specifically tailored to support these applications. Tasks are scheduled based on priority and deadline, and latency is very low in RTOS. In contrast, Normal OS are designed to support general computing environments and are not optimized for time-critical applications. Scheduling in Normal OS is based only on priority, and latency is not as low as in RTOS. RTOS requires hardware with predictable timing characteristics, while Normal OS can operate on most hardware. The kernel of RTOS is designed with minimal functionality, making it quick and reliable, while the kernel of Normal OS has more functionality and power. An example of RTOS is FreeRTOS, and an example of a Normal OS is Microsoft Windows.
The key differences between RTOS and Normal OS lie in their design for time-critical applications, scheduling, hardware, latency, and kernel. RTOS is preferred for real-time applications, while Normal OS is preferred for general computing environments.
