The Algorithm Mergesort, calls the Algorithm Merge. i) Determine the number of comparisons required by Algorithm Merge to merge the arrays A = [12, 15, 26, 29, 36] and B = [2, 5, 14, 25, 35, 47, 49] (ii) Perform a desk trace of the algorithm Merge to show how the arrays A and B are combined. (iii) The computational complexity for Algorithm Merge is O(n) in the worst case. Explain how this was obtained. (iv) Let C(n) be the number of key comparisons required to execute Algorithm Mergesort on a list of n elements. Write a recurrence relation for the number of comparisons made by the algorithm in the worst case. Explain how each term is obtained.
