3.4 It is possible to write nonrecursive programs that implement recursive algorithms using a stack, but at the cost of extra source code complexity (a necessary overhead of using a nonrecursive language like FORTRAN). Write nonrecursive versions of (a) Quicksort; (b) Mergesort. Discuss the difficulties of the added complexity. (c) Which of the two sorts is easier to implement nonrecursively? Why?
