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

大数除法取余，模拟除法过程

#include <stdio.h>
#include <string.h>
using namespace std;

int main()
{
    int i;
    char ch[10000005];
    int mod, cnt = 1;
    while ( ~scanf ( "%s", ch ) )
    {
        int len = strlen(ch);
        mod = 0;
        for ( i = 0; i < len; i++ )
        {
            mod = (mod*10+ch[i]-'0')%10001;
        }
        if ( mod )
        {
            printf ( "Case #%d: NO\n", cnt );
        }
        else
        {
            printf ( "Case #%d: YES\n", cnt );
        }
        cnt++;
    }
}
