C Program to Implement Merge Sort2 min read

In this tutorial, you will learn about the Merge Sort and how to implement in C Program.

Merge Sort Algorithm:

Merge Sort is a sorting algorithm that follows a Divide and Conquer algorithm approach to sort the elements in an array in ascending or descending order.

It divides the array into two halves and sorts them separately. Again the two halves are divided into separate two halves and the process keeps on going until the elements are totally separated. After that, the elements are combined together in the same steps as they were separated but while combining the elements are sorted in each steps.

When the combining step is completed we will get a fully sorted array.

Time Complexity of Merge Sort:

  • Best case:  0(n log n)
  • Average case:  0(n log n)
  • Worst case:  0(n log n)
