Question: Suppose we have an algorithm MEDIAN(A,p,r) that returns the median value of an array A[p . . . r], and assume the worst case running

Suppose we have an algorithm MEDIAN(A,p,r) that returns the median value of an array A[p . . . r], and assume the worst case running time of this algorithm is O(n). If we use this to choose our pivot in (standard) quicksort, explain why the worst-case running time is O(n lg n)? If it simplifies your argument, you may assume all distinct elements
