升序程序：
rest (int a[],int n)
{
    int i,low,high,t;
    for(i=0,low=0,high=n-1;i<=high;)
    {
        if(a[i]>0)
        {
            /*a[i]与a[high]交换，随之high减1*/
            t=a[i];
             a[i]=a[high];
             a[high]=t;
             high--;
         }
      else if (a[i]==0)
           i++;/*略过读元素*/
      else
      {
         /*a[i]与a[low]交换，随之low 增 1，i增  1*/
         t=a[i];
         a[i]=a[low];
         a[low]=t;
         low++;
         i++;
       }
}
}
int s[]={8,4,0,-1,6,0,-5};
main()
/*主函数用于测试rest函数 */
{
  int i;
  clrscr();  /*   */
  printf("\n The arry before rest is:\n");
  for (i=0;i<sizeof(s)/sizeof(s[0]);i++)
      printf("%4d",s[i]);
  rest (s,sizeof(s)/sizeof(s[0]));
  printf("\n The arry after test is:\n");
  for (i=0;i<sizeof(s)/sizeof(s[0]);i++)
      printf("%4d",s[i]);
  printf("\n Press any key to quit...\n");
  getch();
}


谁能帮帮忙把这个升序程序给改成降序程序啊？？
