Q5 (2.33 points): A sorting algorithm is called stable if the relative ordering of equal elements does not change. Thus, for i j, if Ali-AI)], after a stable sort, the element Initially at A[i] ends up before the element initially at Ali]. For example, given A 14 3 10 8 41, the sorted version is -13 4 4 8 10]. In a stable sort, the element A[o (which is 4) will end up as B[1], and the element A4] (which is also 4) will end up at B[2. In a stable sort, the two "4"s wil not switch their order. (This is relevant when sorting an array A of objects, by an integer field (say Ali].key). In a stable sort, the following is always true: ifij and Ali].key-AJ].key, then after sorting, the object initially at Ali] will precede the object initially at Aj].) Show that Mergesort (with a very simple modification/clarification) is stable. Show that Quick sort is not stable, by providing an example
