Web7 nov. 2024 · What is the time complexity of merge sort? This sorting technique is for all kinds of cases. Merge Sort in the best case is O (nlogn). In the worst case, the time complexity is O (nlogn). This is because Merge Sort implements the same number of sorting steps for all kinds of cases. What is the time complexity of bubble sort? WebWorst-case, best-case, and average-case time complexity of merge sort are O(N*logN), making it very efficient. Iterative merge sort is slightly faster than recursive merge sort.
