Web4 Complexity of MergeSort Let us think intuitively what the complexity of MergeSort might be. As seen, the Merge function goes sequentially on the part of the array that it receives, and then copies it over. So the complexity of this step is O(p−q+1). MergeSort does two recursive calls, each on an array which is half the size of the original. WebMay 24, 2024 · The average and worst case time complexity for merge sort is same, but there is another sorting algorithm whose average case is better than merge sort. The best case is O(NlogN) typically, but it can be optimized to O(N) for natural variants. Space complexity of merge sort.
