Write a program for insertion sort.
#include <stdio.h>
#define MAX 20
main()
{
int arr[MAX],i,j,k,n;
printf("Enter the number of elements : ");
scanf("%d",&n);
for (i = 0; i < n; i++)
{
printf("Enter element %d : ",i+1);
scanf("%d", &arr[i]);
}
printf("Unsorted list is :\n");
for (i = 0; i < n; i++)
printf("%d ", arr[i]);
printf("\n");
/*Insertion sort*/
for(j=1;j<n;j++)
{
k=arr[j]; /*k is to be inserted at proper place*/
for(i=j-1;i>=0 && k<arr[i];i--)
arr[i+1]=arr[i];
arr[i+1]=k;
printf("Pass %d, Element inserted in proper place: %d\n",j,k);
for (i = 0; i < n; i++)
printf("%d ", arr[i]);
printf("\n");
}
printf("Sorted list is :\n");
for (i = 0; i < n; i++)
printf("%d ", arr[i]);
printf("\n");
}/*End of main()*/----------------------(BY:- RAVI SINGH)......!
