题意：

给你一个数字n,代表有n组测试数据，后跟n行，每一行第一个数字是吗，代表后面有m个数字，让你求出来这m个数字的和；

代码如下：

import java.util.Scanner;

public class Main {
public static void main(String[] args) {
	Scanner input=new Scanner(System.in);
	int n,m,a,s;
	n=input.nextInt();
	while(true) {
		if(n==0)
			break;
		n--;
		m=input.nextInt();
		s=0;
		for(int i=0;i
