The figure below shows how the time increases when running Merge Sort on an array withnnvalues. The difference between best and worst case scenarios for Merge Sort is not as big as for many other sorting algorithms. Merge Sort Simulation ...
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)...

Hence the time complexity is of the order of [Big Theta]:O(nLogn). Worst Case The worst-case time complexity is [Big O]:O(nLogn). Best Case Space Complexity Space Complexity for Merge Sort algorithm isO(n)becausenauxiliary space is required for storing the sorted subarray in the auxilia...

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. ...
Merge sort further follows the following time complexity, thus making the entire algorithm efficient and fast as per requirement and implementation, which is as follows: If we try to estimate the worst-case time complexity, then it will be O (n*logn) ...

3. Complexity Analysis The following describes the runtime complexity of mergesort. Mergesort sorts in worst case in O(n log n) time. Due to the required copying of the collection Mergesort is in the average case slower than Quicksort. 4. Links and Literature Nothing listed. 4.1. vogella...
