WebAug 5, 2024 · The time complexity of Merge Sort is: O (n log n) And that is regardless of whether the input elements are presorted or not. Merge Sort is therefore no faster for sorted input elements than for randomly … 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.

WebSpace Complexity of merge sort using a queue . ... Hi, I wanted to confirm the space complexity of this algorithm. I think it is O(N) (big-OH). because the queue holds atmost N elements at any given time. and the merge function will have atmost N recursive calls, so the stack will hold N calls. ... WebFeb 18, 2016 · Merge sort is a divide and conquer algorithm. Think of it in terms of 3 steps - The divide step computes the midpoint of each of the sub-arrays. Each of this step just takes O (1) time.The conquer step recursively sorts two subarrays of n/2 (for even n) elements each.The merge step merges n elements which takes O (n) time.
