Merge Sort Algorithm is considered as one of the best sorting algorithms having a worst case and best case time complexity of O(N*Log(N)), this is the reason that generally we prefer to merge sort over quicksort as quick sort does have a worst-case time complexity of O(N*N)...
Merge Sort and Quick Sort are both efficient sorting algorithms. Merge Sort has a consistent time complexity of O(n log n), while Quick Sort has an average time complexity of O(n log n) but can degrade to O(n^2) in the worst case. ...
In this article, we discussed two sorting algorithms: Quicksort and Mergesort. We learned how these methods worked in action and compared them in terms of space, and time complexity, and other properties such as stability and in-place sorting....
Time Complexity: The list of sizeNis divided into a max oflogNparts, and the merging of all sublists into a single list takesO(N)time, the worst case run time of this algorithm isO(NLogN) Contributed by: Anand Jaisingh Did you find this tutorial helpful?
Other names: mergesort Quick reference Complexity Worst case time O(nlgn)O(nlgn) Best case time O(nlgn)O(nlgn) Average case time O(nlgn)O(nlgn) Space O(n)O(n) Strengths: Fast. Merge sort runs in O(nlg(n))O(nlg(n)), which scales well as nn grows. ...
As a result, it makes more sense to think about merge sort in terms of the number of operations performed on a single level of the tree. At each level, a total of n operations take place, and there are log(n) + 1 levels; consequently, the overall time complexity is O(n * log(n...
Among the particular advantages of mergesort --- also compared to Quicksort and its variants --- it maintains its O(N log N) time complexity also in the worst case (in fact the worst case time is only O(N) worse than the average time) and it is stable. There are two basic ...

Though Merge Sort is reliable and stable (with time complexity O(n log n)), it's not the best every time. Its principal disadvantage is that it requires additional memory space. Quick Sort would generally be the preferred option, and in certain special situations, Bucket and Radix Sort ...
