1) Is mergesort a stable sort algorithm? What about quicksort? Provide examples to justify your answer. 1A) A list A[0. . .n - 1] contains n real nubmers. A pair (Ai;Aj) is defined as an inversion if the elements of the pair are out-of-order in the list A. Define an O(n * log(n)) algorithm for counting the number of inversions in A.
