Problem Description

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

There is 73 days in Xixi a year and 137 days in Haha a year.

Now you know the days N after Big Bang, you need to answer whether it is the first day in a year about the two planets.

 

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.

 

Sample Input

10001 0 333

 

Sample Output

Case #1: YES Case #2: YES Case #3: NO

 

 

#include <cstdio>
#include <vector>
#include <cstring>
#include <algorithm>
using namespace std;
const int maxn=1e8+5;
char s[maxn];
int ans,c;

int main(){
    while(~scanf("%s",s)){
        ans=0;
        int len=strlen(s);
        for(int i=0;i<len;i++)
            ans=(ans*10+s[i]-'0')%10001;
        if(!ans){
            printf("Case #%d: YES
",++c);
        }
        else printf("Case #%d: NO
",++c);
    }

}
