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)
Correct answer is option 'D'. Can you explain this answer?

Suppose we have a O(n) time algorithm that finds median of an unsorted...
If we use median as a pivot element, then the recurrence for all cases becomes T(n) = 2T(n/2) + O(n) The above recurrence can be solved using Master Method. It falls in case 2 of master method.
