Merge sort algorithm in C++ with example: In this tutorial, we will learn about the merge sort algorithm and the implementation of merge sort using the C++ program.
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 The...
#include <iostream> #include <algorithm> using namespace std; const int N = 1e5+10; int n; int q[N],p[N]; long long ans; void merge_sort(int q[],int l,int r) { if(l>=r) return; int mid = l + r >> 1; merge_sort(q,l,mid); merge_sort(q,mid+1,r); int i=l,...
As shown in the above pseudo code, in merge sort algorithm we divide the array into half and sort each half using merge sort recursively. Once sub-arrays are sorted individually, the two sub-arrays are merged together to form a complete sorted array. Pseudo Code For Merge Sort Following is...
