Count swaps required to sort an array using Insertion Sort

WebIn particular, merge sort runs in \Theta (n \lg n) Θ(nlgn) time in all cases, and quicksort runs in \Theta (n \lg n) Θ(nlgn) time in the best case and on average, though its worst-case running time is \Theta (n^2) Θ(n2). Here's a table of these four sorting algorithms and their running times: Divide-and-conquer WebNow we have to figure out the running time of two recursive calls on n/2 n/2 elements. Each of these two recursive calls takes twice of the running time of mergeSort on an (n/4) (n/4) -element subarray (because we have to halve n/2 n/2) plus cn/2 cn/2 to merge. We have two subproblems of size n/2 n/2, and each takes cn/2 cn/2 time to merge, and ... dialysis center market share
