- In this tutorial you will get program for merge sort in C. Merge sort runs in O (n log n) running time. Quick Sort in C [Program & Algorithm].
- The merge sort is a sort where the operation of sorting is closely related to the process of merging. Let assume that there are two arrays that can be combined to produce a single sorted array. This process can be accomplished easily by successively selecting the record with the smallest key occurring in either of the tables and placing this record in.

Merge sort runs in O (n log n) running time. It is very efficient sorting algorithm with near optimal number of comparison. Used for merge sort comes under the category of divide and conquer technique. An array of n elements is split around its center producing two smaller arrays. After these two arrays are sorted independently, they can be merged to produce the final sorted array.

Quick Sort Program
The process of splitting and merging can be carried recursively till there is only one element in the array. An array with 1 element is always sorted. ↓. ama Yes Yes Yes.I do have a doubt.
Mergesort(a,i,mid); //left recursion mergesort(a,mid+1,j); //right recursion As per my understanding left recursion will execute until the condition is false and then the control moves over to the right recursion. My question is at mergesort(a,mid+1,j),the new values of mid,low and high will be from main function? OR from the mergesort(a,i,mid)? And the same question applies here too: mergesort(a,mid+1,j); //right recursion merge(a,i,mid,mid+1,j); //merging of two sorted sub-arrays.
