Write a program to compute the exact value of the number of array accesses used by top-down mergesort and by bottom-up mergesort. Use your program to plot the values for N from 1 to 512, and to compare the exact values with the upper bound 6N lg N.

Given the following, write a line of code that will initialize p to point to the “7” inthe array).unsigned char x[] = {2, 3, 5, 7, 11, 13, 17};unsigned char *p, *q; If pointer q in the previous question points to some element of array x, whatexpression will return the index of the element pointed to? E.g., if q points to the 13in the above array, then your expression should return 5 In C Programming Please!

Question: Given an array of integers, find the maximum sum of contiguous subarray (containing at least one number). Example: Input: [-2,1,-3,4,-1,2,1,-5,4] Output: 6 (Explanation: [4,-1,2,1] has the largest sum = 6)

Given the following array of integers 123, 2154, 222, 4, 283, 1560, 1061, 2150 If we want to sort the array using radix-sort, what will be the content of the array after the second pass? 1560, 2150, 1061, 222, 123, 283, 2154, 4 О 4, 1061, 123, 2150, 2154, 222, 283, 1560 О4, 222, 123, 2150, 2154, 560, 61, 283 4, 222, 123, 2154, 2150, 1560, 1061, 283 O None of the above
