Merge Sort Time ComplexityThe Merge Sort algorithm breaks the array down into smaller and smaller pieces.The array becomes sorted when the sub-arrays are merged back together so that the lowest values come first.The array that needs to be sorted has nn values, and we can find the time ...

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 Algorithm is considered as one of the best sorting algorithms having a worst case and best case time complexity ofO(N*Log(N)), this is the reason that generally we prefer tomerge sortover quicksort as quick sort does have a worst-case time complexity ofO(N*N). ...
Time Complexity Average Case Merge sort is a recursive algorithm. The following recurrence relation gives the time complexity expression for Merge sort. This result of this recurrence relation givesT(n) = nLogn.We can also see it as an array of size n being divided into a maximum ofLognparts...
1. Worst Case:The case when all the array elements are sorted in the reverse order. Using Masters theorem, we found the complexity of Merge sort in such case is Θ(nlogn). 2. Average Case:This is the case when the elements are partially sorted. The complexity of merge sort, in this...
Merge sort was unique for its time in that the best, worst, and average time complexity are all the same:Θ(N*log(N)). This means an almost-sorted list will take the same amount of time as a completely out-of-order list. This is acceptable because the worst-case scenario, where a...
