1. 1. /* Write C program that implement the following sorting methodsto sort a given list of integers in ascending order: ii) Quick sort */#include <stdio.h>#define MAX 10void swap(int *m,int *n){ int temp; temp = *m; *m = *n; *n = temp;}int get_key_position(int x,int y ){ return((x+y) /2);}// Function for Quick Sortvoid quicksort(int list[],int m,int n){ int key,i,j,k; if( m < n) {
