Suppose we have an O(n) time algorithm that finds the median of an unsorted array. Now consider a QuickSort implementation where we first find median using the above algorithm, then use median as the pivot. What will be the worst-case time complexity of this modified QuickSort? (A) O(n^2 Logn) (B) O(n^2) (C) O(n Logn Logn) (D) O(nLogn) (E) O(n)
