Problem Description

Two planets named Haha and Xixi in the universe and they were created with the universe beginning.

There is 73 days

Input

There are several test cases(about 5 huge
test cases).

For each test, we have a line with an only integer N(0≤N),
the length of N is
up to 10000000.

 

Output

For the i-th test case, output Case #i: , then output "YES" or "NO" for the answer.

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");
}
}
