Someone help please Let A be an array of 5 integers, whose contents are as follows: 3, 2, 1, 5, 4 We will apply quick sort to sort this array. Show all of the element-wise comparisons made by the algorithm in the correct order. Here an element-wise comparison means the comparison of one element of the array with another element of the array or the key set in a particular step of the algorithm. Since the algorithm may move the...

Please show work clearly. Thanks 4. Suppose you had n matrices with dimensions: ai xbi ,a2 x b2. . . . ,a,, X bn. Your goal is to determine, given two integers s and t, whether it is possible to multiply a sequence from the list of given matrices together, in any order and possibly not using all of the matrices, to end up with a matrix with dimensions s × t. For example, if the list of matrix dimensions...

The input consists of n numbers a1, a2, . . . , an and a target value t. The goal is to determine in how many possible ways can we add up two of these numbers to get t. Formally, your program needs to find the number of pairs of indices i, j, i < j such that ai+aj = t. For example, for 2, 7, 3, 1, 5, 6 and t = 7, we can get t in two...
