发工资咯：

#include<stdio.h>
int num=0;
void fun(int x)
{
  num+=x/100;
  x=x%100;
  num+=x/50;
  x=x%50;
  num+=x/10;
  x=x%10;
  num+=x/5;
  x=x%5;
  num+=x/2;
  x=x%2;
  num+=x/1;
}
int main( )
{
 int N,i,t;
 while(scanf("%d",&N)!=EOF,N)
 {
  for(i=1;i<=N;i++)
  {
   scanf("%d",&t);
   fun(t);
  }
  printf("%d\n",num);
}
return 0;
}
