TheMerge Sort algorithmbreaks 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 hasnnvalues, and we can find the time complexity by start looking at ...
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. ...

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...
Best Case Time Complexity [Big-omega]: O(n*log n)Average Time Complexity [Big-theta]: O(n*log n)Space Complexity: O(n)Time complexity of Merge Sort is O(n*Log n) in all the 3 cases (worst, average and best) as merge sort always divides the array in two halves and takes ...
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...
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...
