总结：打卡题，直接大数取模过

#include<iostream>#include<string>#include<cstdio>int const maxn=10000000+10;char str[maxn];using namespace std;int main(){   //freopen("/Users/zhangjiatao/Documents/暑期训练/input.txt","r",stdin);    int t=0;    while(scanf("%s",str)!=EOF)    {        t++;        int i;        int rem=0;        for(i=0;str[i];i++){            rem=rem*10+str[i]-'0';            rem=rem%10001;        }        printf("Case #%d: ",t);        if(rem==0) printf("YES\n");        else printf("NO\n");    }}
