Assume that are given a "black-box" (i.e., you do not have the source code) procedure MEDIAN that takes as parameters an array A and subarray indices p and r, and returns the value of the median element of A[p . . r] in O(n) time in the worst case. Give a simple, linear-time algorithm that uses this procedure MEDIAN to find the ith smallest element. Write the recurrence relation for you algorithm and show the solution is linear growth.
