Sorting large datasets: Merge sort is particularly well-suited for sorting large datasets due to its guaranteed worst-case time complexity of O(n log n).

Since there are passes, the total computing time is O(nlogn). As merge showed, we can merge two sorted segments in linear time, which means that each pass takes O(n) time. The first pass merges segments of size 1, the second merges segments of size 2, and the pass merges segments of size 2 i-1. Analysis of Merge Sort:Ī merge sort consists of several passes over the input. Merge sort can be made more efficient by replacing recursive calls with Insertion sort for smaller array sizes, where the size of the remaining array is less or equal to 43 as the number of operations required to sort an array of max size 43 will be less in Insertion sort as compared to the number of operations required in Merge sort. How can we make Merge sort more efficient? No, In merge sort the merging step requires extra space to store the elements. So N auxiliary space is required for merge sort.

It falls in case II of the Master Method and the solution of the recurrence is θ(Nlog(N)). The time complexity of Merge Sort isθ(Nlog(N)) in all 3 cases (worst, average, and best) as merge sort always divides the array into two halves and takes linear time to merge two halves.Īuxiliary Space: O(n), In merge sort all elements are copied into an auxiliary array. The above recurrence can be solved either using the Recurrence Tree method or the Master method. Merge Sort is a recursive algorithm and time complexity can be expressed as following recurrence relation. Time Complexity: O(N log(N)), Sorting arrays on different machines.
