Write a c program for Merge short.

Solution:
#include <stdio.h>
#include<conio.h>
#define max 10

int a[11] = { 10, 14, 19, 26, 27, 31, 33, 35, 42, 44, 0 };
int b[11];

void merging(int low, int mid, int high) {
   int l1, l2, i;

   l1 = low;
   l2 = mid + 1;
   for(i = low; l1 <= mid && l2 <= high; i++) {
      if(a[l1] <= a[l2])
      {
b[i] = a[l1];
l1++;
      }
      else
         b[i] = a[l2++];
   }
   
   while(l1 <= mid)    
      b[i++] = a[l1++];

   while(l2 <= high)   
      b[i++] = a[l2++];

   for(i = low; i <= high; i++)
      a[i] = b[i];
}

void sort(int low, int high) {
   int mid;
   
   if(low < high) {
      mid = (low + high) / 2;
      sort(low, mid);
      sort(mid+1, high);
      merging(low, mid, high);
   } else { 
      return;
   }   
}

int main() { 
   int i;

   printf("List before sorting\n");
   
   for(i = 0; i <= max; i++)
      printf("%d ", a[i]);

   sort(0, max);

   printf("\nList after sorting\n");
   
   for(i = 0; i <= max; i++)
      printf("%d ", a[i]);
      getch();
}
