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. option are A)O(n^2 Logn) B)O(n^2) C)O(n Logn Logn) D)O(nLogn) D)O(nLogn)
