1.	What is the average case time complexity of merge sort?(a) O(n log n)(b) O(n^2)(c) O(n^2 log n)(d) O(n log n^2)I had been asked this question during a job interview.This key question is from Sorting in section Sorting of Data Structures & Algorithms II
Answer» Correct choice is (a) O(N log n) The best I can explain: The RECURRENCE RELATION for MERGE sort is given by T(n) = 2T(n/2) + n. It is found to be equal to O(n log n) using the master theorem.
