A list of n string, each of length n, is sorted into lexicographic order using the merge-sort algorithm. The worst case running time of this computation is
  • a)
    O (n log n)
  • b)
    O (n2 log n)
  • c)
    O (n2 + log n)
  • d)
    O (n2)
Correct answer is option 'B'. Can you explain this answer?

The recurrence tree for merge sort will have height Log(n). And O(n2) work will be done at each level of the recurrence tree (Each level involves n comparisons and a comparison takes O(n) time in worst case). So time complexity of this Merge Sort will be O (n2 log n).
