Let A be an array of n numbers. Suppose that you have an algorithm Algo() that finds the median of any array of numbers1 in time linear in the number of elements of the array (that is, in O(#elements in the array)). Show how, using Algo(), Quick Sort can be modified so that it runs in O(n lg n) time in the worst case. Write a pseudocode for the modified Quick Sort, and analyze its running time by describing its recurrence relation and solving it. You
