hdu 1002(大数加法)

题目大意：输入a、b，输出a与b之和

解题思路:这道题的特点就在于。整数数据的长度超过了整数类型的最大长度long。这时我们可以考虑用java来解决

代码如下：

package com.njupt.acm;//提交时把这一行去掉

import java.math.BigInteger;
import java.util.Scanner;

public class HDU_1002_2 {//提交时把类名换成Main

	public static void main(String[] args) {
		Scanner scanner = new Scanner(system.in);
		
		while(scanner.hasNextInt()){
			int t = scanner.nextInt();
			BigInteger a,b,c;
			int i = 0;
			int count = 1;
			while( i < t ){
				a = scanner.nextBigInteger();
				b = scanner.nextBigInteger();
				c = a.add(b);
				if(count != 1){
					System.out.println();
				}
				
				System.out.println("Case "+count+++":");
				System.out.println(a+ " + " +b+" = "+c);
				++i;
			}
			
		}
		
	}
}
