输入一组数据，求出在排序中数据交换的次数

#include<stdio.h>
int main()
{
 int a[1010],i,j,sum,n,temp;
 while(scanf("%d",&n)!=EOF)
     {
      sum=0;
      for(i=0;i<n;i++)  
         scanf("%d",&a[i]);
      for(j=1;j<n;j++)
         for(i=0;i<n-j;i++)
            if(a[i]>a[i+1])
              {
               temp=a[i];
               a[i]=a[i+1];
               a[i+1]=temp;
               sum++;
              }
      printf("Minimum exchange operations : %d\n",sum);
     } 
 return 0;
