- You are to create a program that enables you to measure the execution times of various sorting algorithms to better understand their efficiency characteristics. For each sorting algorithm, you are to measure and record the execution times for various lists of randomly generated integers. The list sizes used for the test cases should start at 10,000, and go up by 10,000 for each test until the execution time for the test exceeds 60 seconds. The algorithms for which you are to run the tests are: • Selection sort • Bubble sort • Merge sort# Exercise 1. Implement the algorithm covered in lectures that determines if an integer n is prime. Your function should return True, if n is prime, and False otherwise. Your algorithm has to be effective for n ~ 1,000,000,000,000.def isPrime(n):Write a program to read and store four student's id number and their grade, sort them into an order their id, based on grades from the smallest to the largest, then print them out. The student's id number and their grade values should be typed in by the user in response to a prompt message.
- Fifty students in a class appeared in their final examination. The division column of their mark sheets contains the division (FIRST, SECOND, THIRD, or FAIL) obtained by them. If their mark sheets are available with you, write an algorithm to calculate and print the total nuner of students who passed in FIRST division. rithm.The first time you run algorithm A on a dataset of n elements; it is faster than algorithm B. The second time you run algorithm A on a dataset of n elements; it is slower than algorithm B. Explain how this is possible. Give an example for algorithm A and algorithm B.You are given two different methods for sorting the values in an array: Sort1 and Sort2. You have determined that Sort1 = O(nlog n) and Sort2 = O(n2). You need to choose one of these two sorting methods to sort lists in a program you are writing, but you would like to choose the one which completes the fastest. Given this information, is either of these two methods guaranteed to be complete faster than the other? If so, explain which one is faster and why. If not, explain why not.

But I am confused as to how to find the key matrix in the first place with the information given.•Write an algorithm to calculate the sum of a set of values (we don't know their count).

- You are requested to create an algorithm analyzer for a sorting program. You are tasked to meet the requirements below: a. Create a program that will sort a maximum of ten values. Values can either be numeric or string. b. Apply one sorting technique for your solution. You can select from the sorting techniques presented below. 1. Bubble 2. Merge c. Compute the time complexity of your solution using the Big Oh algorithm and determine the order of complexity.You have an array of 10,000 subject scores for a high-school exam and you want to find the scores that are ranked from 4900 to 5100 that is the 201 most middle-ranked scores. Precisely describe two alternative algorithmic ap proaches to doing this - one of which is, in terms of time complexity, more efficient than the other.One of the things discussed in this chapter is the sorting of data. Imagine that a large medical center hires you to write a program that displays a list of potential organ recipients. The hospital's transplant team will consult this list if they have an organ available for transplant. The hospital administrators have instructed you to sort potential recipients by last name and display them in alphabetical order. If more than 10 patients are waiting for a particular organ, the first 10 patients will be displayed; a doctor can either select one or move on to view the next 10 patients. You are concerned that this program will unfairly select patients whose last names begin near the front of the alphabet. It's critical that the hospital has a program written quickly, as the hospital currently has no method of going through potential organ recipients. Based on this, answer the following questions in detail: Would you write and install the program? If yes, would you change anything about…
