hdu1047(大数)

大数相加，注意格式。

下面是代码：

import java.math.*;
import java.util.*;
public class Main {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		BigInteger a;
		BigInteger c=new BigInteger("0");
		Scanner read=new Scanner(System.in);
		int n;
		n=read.nextInt();
		//System.out.println(n);
		while(n-->0){
			BigInteger b=new BigInteger("0");
			a=read.nextBigInteger();
			
			while(!a.equals(c)){
				b=b.add(a);
				a=read.nextBigInteger();
				//System.out.println(a);
			}
			System.out.println(b);
			if(n!=0)
			System.out.println();
			
		}
		

	}

}
