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();            }        }    }}
