见代码即可明白。

#include<stdio.h>int cal(int n){    int sum=0;    sum+=n/100;    n%=100;    sum+=n/50;    n%=50;    sum+=n/10;    n%=10;    sum+=n/5;    n%=5;    sum+=n/2;    n%=2;    sum+=n;    return sum;}int main(){    int n,a[105],ans;    while(~scanf("%d",&n))    {        ans=0;        if(n==0)            break;        for(int i=0; i<n; i++)        {            scanf("%d",&a[i]);            ans+=cal(a[i]);        }        printf("%d\n",ans);    }    return 0;}
