用java写大数果然是方便多了！

 1 import java.math.BigInteger;

 2 import java.util.*;

 3 import java.io.*;

 4  

 5 public class Main{

 6     public static void main(String[] args){

 7         Scanner cin = new Scanner(System.in);

 8         int n = cin.nextInt();

 9         for(int i = 1; i <= n; i++){

10             BigInteger x = cin.nextBigInteger();

11             BigInteger y = cin.nextBigInteger();

12             System.out.print("Case "+i+": ");

13             if(x.remainder(y).equals(BigInteger.ZERO)){

14                 System.out.println("divisible");

15             }else

16                 System.out.println("not divisible");

17         }

18     }

19 }
