- (Statistics) a. Write a C++ program that reads a list of double-precision grades from the keyboard into an array named grade. The grades are to be counted as they’re read, and entry is to be terminated when a negative value has been entered. After all grades have been input, your program should find and display the sum and average of the grades. The grades should then be listed with an asterisk (*) placed in front of each grade that’s below the average. b. Extend the program written for Exercise 1a to display each grade and its letter equivalent, using the following scale: Between90and100=AGreaterthanorequalto80andlessthan90=BGreaterthanorequalto70andlessthan80=CGreaterthanorequalto60andlessthan70=DLessthan60=F(Numerical) Given a one-dimensional array of integer numbers, write and test a function that displays the array elements in reverse order.(Data processing) The answers to a true-false test are as follows: T T F F T. Given a twodimensional answer array, in which each row corresponds to the answers provided on one test, write a function that accepts the two-dimensional array and number of tests as parameters and returns a one-dimensional array containing the grades for each test. (Each question is worth 5 points, so the maximum possible grade is 25.) Test your function with the following data:
- Computer Science 1)What are the steps in the selection sort algorithm? Group of answer choices Split the array into two subarrays, sort each subarray, and append the two arrays together. Starting at index 0, search the entire array to find the smallest value and swap the smallest value with the value at index 0. 2)Suppose there an integer threshold such that the expression n2 is equal to the expression 9n-8 at that threshold, and is larger for all integers values larger than the threshold. What does this mean?Help on the following question? Code Review Section Your co-worker has developed a function to find the median value in an unsorted array with an odd number of elements. For arrays with an even number of elements, this function does not apply. To normally find such a value would be to sort the array and then obtain the value at the middle index of the array. For example, [5 2 53 1 4], the median is 4 because when it is sorted, the array will be [1 2 4 5 53] and the value at the middle index is 4. Your co-worker’s function uses the partition function that is the same function as the one the QuickSort algorithm uses. Here’s the code he shows you: public static int[] array = {6, 1, 20, 10, 4}; public static int findMedian(int lo, int hi, int medianIndex) { int partitionIndex = partition(lo, hi); if (medianIndex == partitionIndex) return partitionIndex; if (medianIndex > partitionIndex) return findMedian(partitionIndex + 1, hi,…C program for the longest sequence of increasing numbers for one array. Use the function: void longestSequence(int b[], int sizeB)
