Suppose we have a O(n) time algorithm that finds median of an unsorted array.Now consider a QuickSort implementation where we first find median using the above algorithm, then use median as 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)
