Answers
(a) To find the intersection of two sets represented by arrays A and B, we can use a hash set data structure. We iterate through each element in A and insert them into the hash set. Then, we iterate through each element in B and check if it exists in the hash set. If it does, we add it to the result array C. This algorithm has a time complexity of O(n + m), where n is the size of array A and m is the size of array B.
1. Create an empty hash set.
2. Iterate through each element in array A:
- Insert the element into the hash set.
3. Create an empty result array C.
4. Iterate through each element in array B:
- Check if the element exists in the hash set.
- If it does, add the element to array C.
5. Return array C as the intersection of the two sets.
The algorithm works by using a hash set to efficiently check for the existence of elements. Inserting elements into a hash set and checking for membership can be done in O(1) average case time complexity. Therefore, the overall time complexity of the algorithm is O(n + m), where n is the size of array A and m is the size of array B. This is because we perform O(1) operations for each element in A and B, resulting in a linear time complexity. The ordering of the elements in the result array C does not matter, as stated in the example.

Define the parameters to be programmed in so TMR2 will generate an overflow every 0.032 seconds.
Answers
The pre-scaler should be set to 1:8, and the TMR2 register should be loaded with a value of 6Dh.
To program the TMR2 to generate an overflow every 0.032 seconds, we need to define the following parameters: Prescaler: It is a device that can be used to divide down the input clock frequency before it reaches the TMR2. It helps in generating the desired output frequency. The prescaler is a 1:8 prescaler in this case since 0.032 seconds is a short period.TMR2 Register: It is the actual 8-bit TMR2 timer register that will be incremented every time a clock cycle is received. When TMR2 is incremented from FFh to 00h, it triggers an interrupt or overflow event. In this case, the value in the TMR2 register should be set to 6Dh, which is equal to 109 in decimal, for an overflow period of 0.032 seconds. Clock Source: A clock source is needed to increment the TMR2 register.
For this case, we will use an internal instruction clock (Fosc/4), which is the default clock source. We need to define the TMR2 register and prescaler values that correspond to a period of 0.032 seconds with a given clock source. The TMR2 register and prescaler values that correspond to an overflow period of 0.032 seconds can be calculated using the following formula: TMR2 = (desired time/(4*prescaler))-1TMR2 = (0.032 s/(4*8))-1TMR2 = 109 Decimal value of 109 is 6Dh.

Answers
The question is poorly formatted:
#include <stdio.h>
int main() {
int arr [5] = {1, 2, 3, 4, 5};
arr [1] = 0;
arr [3] = 0;
for (int i = 0;i < 5; i+=1)
printf("%d", arr[i]);
return 0;
}
Answer:
The output is 10305
Explanation:
I'll start my explanation from the third line
This line declares and initializes integer array arr of 5 integer values
int arr [5] = {1, 2, 3, 4, 5};
This line sets the value of arr[1] to 0
arr [1] = 0;
At this point, the content of the array becomes arr [5] = {1, 0, 3, 4, 5};
This line sets the value of arr[3] to 0
arr [3] = 0;
At this point, the content of the array becomes arr [5] = {1, 0, 3, 0, 5};
The next two lines is an iteration;
The first line of the iteration iterates the value of i order from 0 to 4
for (int i = 0;i < 5; i+=1)
This line prints all elements of array arr from arr[0] to arr[4]
printf("%d", arr[i]);
So, the output will be 10305

A support technician uses the ping utility on a system that is online, yet no response is received. What should be allowed through a firewall, for ping to operate correctly?
Answers
Answer:
Internet Control Message Protocol (ICMP) Echo Requests
Explanation:
A system that has Windows Firewall or antivirus or other third party antivirus enabled with their configuration setting set to default, ping command from another device will not be able to see if the device with an enabled firewall is alive.
The ping command sends Internet Control Message Protocol (ICMP) Echo Request to a destination device after the destination device will reply with a Reply packet. However, by default, firewalls, such as Windows firewall blocks ICMP Echo Requests from the external network and pinging will work when the firewall is disabled or an exception is created that lets ICMP Echo Requests pass through the firewall.
The Internet Control Message Protocol (ICMP) should be allowed through a firewall, for ping to operate correctly.
ICMP (Internet Control Message Protocol) is a protocol that produces error messages to the Internet protocol address.This error reporting protocol (ICMP) is used for diagnostics and network management.Any network device using TCP/IP can send, receive, and/or process ICMP messages.In conclusion, the Internet Control Message Protocol (ICMP) should be allowed through a firewall, for ping to operate correctly.

She has 10GB of type A memory that can being used to store A objects, and reading an object from this memory takes 1ms. The second type of memory, type Z, is a lot slower, but it's cheap, and so Alice bought a lot of it. She has 1TB of the second type of memory that she can use to store objects, and reading an object from this memory takes 100ms. Alice decides she's going to build a system where she keeps all of her objects in the second type of memory, and then also keeps copies of some of those objects in the first type so that she can do some of her reads more quickly. Alice has 2048 objects, all of the same size, which use up all of her second type of memory storage. Alice decides to analyze different ways to pick and choose what she keeps in her type A memory, and how they affect her expected object read performance.

Answers
If Alice is naïve and decides to randomly fill her type A memory with objects and never change it, her expected time to read 10 randomly selected objects out of the 2048 would be 50ms.

If Alice decides to improve her performance by putting an object in her type A memory every time she reads it and removing the least recently read object when she needs to remove something, in the best case scenario, her average read time per object would be 1ms.

Jackson has been working as a sales manager at a large company for 8 months and oversees about 100 sales representatives. For the most part, Jackson does a good job of motivating his employees and overall team sales have remained consistent. However, Jackson has a particularly dominating management style. He tends to micro-manage and tells even the most successful sales reps with 20+ years of experience how they should be doing their jobs. He has called out several sales reps in a meeting and put them on the spot to justify their sales techniques. Jackson does not respond very well to criticism from other people.
a.Thoroughly analyze why the conflict has occurred.
b.Identify and explain how this conflict can be viewed and resolved from the point of view of one of Jackson’s employees.
c.Identify and explain how this conflict can be viewed and resolved from the point of view of one of Jackson’s managers.
Answers
Answer:
a. The conflict in this situation has occurred because of Jackson's dominating management style. He tends to micro-manage and control every aspect of his employees' work. This type of management style can be demotivating and may lead to conflicts between the manager and employees. Additionally, Jackson's tendency to call out sales reps in meetings and put them on the spot can make them feel embarrassed and demoralized.
b. From the point of view of one of Jackson's employees, the conflict can be viewed as a result of Jackson's lack of trust in his employees. They may feel that Jackson does not have faith in their abilities and that he is overly critical of their work. To resolve this conflict, Jackson should start delegating more responsibilities to his employees and trust them to make decisions and work independently. He should also recognize and appreciate their successes, rather than just focusing on their mistakes.
c. From the point of view of one of Jackson's managers, the conflict can be viewed as a result of his management style. Jackson's micro-managing approach may lead to inefficiencies and delays in decision-making, as employees may feel that they cannot make decisions without his approval. To resolve this conflict, Jackson's managers should provide him with feedback on his management style and encourage him to delegate more responsibilities to his employees. They should also provide him with training on how to manage employees effectively and how to give feedback in a constructive and respectful manner.
