Merge the sorted halves. There is something known as the Two Finger Algorithm that helps us merge two sorted arrays together. Using this subroutine and calling the merge sort function on the array halves recursively will give us the final sorted array we are looking for.

WebExecution of Merge sort in C++. 1.) Divide Step: First of all the array will be divide in to N sub list, until each sub list contains only one element. 2.) Conquer Step: Take two sub list and place them in logical order. 3.) Combine Step: Web25 mei 2024 · After this use some sorting algorithm, like merge sort to sort the list in the ascending order. That’s it! the problem is solved. However, this approach is not so efficient as it does not take the advantage of the fact that each linked list is already sorted. This method has the time complexity of O(n.log(n)).
