The 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 complexity by start looking ...
Merge sort is a recursive algorithm that works like this: split the input in half sort each half by recursively using this same process merge the sorted halves back together Like all recursive algorithms, merge sort needs a base case. Here, the base case is an input list with one it...
Merge Sort Algorithm But today we'll be focusing onMERGE SORTand the main reason of casting light upon this sorting algorithm is it takesO(N*logN)time which is very efficient with respect to theO(N*N). Merge Sort Algorithm is considered as one of the best sorting algorithms havi...
Merge Sort Algorithm Complexity 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 divi...
As shown in the image below, the merge sort algorithm recursively divides the array into halves until we reach the base case of array with 1 element. After that, the merge function picks up the sorted sub-arrays and merges them to gradually sort the entire array. Merge sort in action Th...

Below is a Python implementation of the Merge Sort algorithm. merge_sort.py def merge_sort(arr): if len(arr) > 1: mid = len(arr) // 2 left_half = arr[:mid] right_half = arr[mid:] merge_sort(left_half) merge_sort(right_half) i = j = k = 0 while i < len(left_half) ...
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?
