Mar 14, 2024 · The Time Complexity of Merge Sort is O (n log n) in both the average and worst cases. The space complexity of Merge sort is O (n).

In computer science, merge sort (also commonly spelled as mergesort or merge-sort[2]) is an efficient and general purpose comparison-based sorting algorithm. Most implementations of merge sort are …

Explore the time complexity of Merge Sort in-depth, including best, average, and worst-case analysis, and comparison with other sorting algorithms.

The figure below shows how the time increases when running Merge Sort on an array with \ (n\) values. The difference between best and worst case scenarios for Merge Sort is not as big as for many other …

Dec 29, 2025 · Unlike QuickSort (which can degrade to O (n²) in the worst case) or Bubble Sort (O (n²) time), Merge Sort guarantees O (n log n) time complexity across all scenarios (best, average, and …

Jun 14, 2025 · A: Mergesort has a consistent time complexity of O (n log n) O(nlogn) across all cases, making it a reliable choice for sorting large datasets. Other algorithms like Quicksort and Heapsort …

Merge Sort is an efficient and stable sorting algorithm suitable for large datasets. Although it requires additional memory, its predictable time complexity of O (n log n) makes it a popular choice in many …

Merge Sort has a time complexity of O (n log n) in all cases: best, average, and worst. This makes it highly efficient compared to algorithms like Bubble Sort (O(n²)) for large datasets.

Feb 14, 2026 · Merge sort is a way to sort a list of items, like numbers or names, in order. Imagine you have a big pile of mixed-up playing cards, and you want to sort them. You can break the pile into …
