HDU-1002-A + B Problem II

大数问题还是java方便

import java.math.BigInteger;
import java.util.Scanner;
public class Main{
    public static void main(String[] args) {
        Scanner cin=new Scanner(System.in);
        while(cin.hasNext()){
            int n=cin.nextInt();
            for(int i=1;i<=n;i++){
                BigInteger a=cin.nextBigInteger();
                BigInteger b=cin.nextBigInteger();
                System.out.println("Case "+i+":");
                System.out.println(a+" + "+b+" = "+a.add(b));
                if(i!=n) System.out.println();
            }
        }
    }
}
