Problem Description

Your task is to calculate the sum of some integers.

Input

Input contains an integer N in the first line, and then N lines follow. Each line starts with a integer M, and then M integers follow in the same line.

Output

For each group of input integers you should output their sum in one line, and with one line of output for each line in input.

Sample Input

C语言AC代码：

#include <stdio.h>
int main()
{
    int n,m,x,sum;
    scanf("%d",&n);

        while(n--)
        {
            scanf("%d",&m);
            sum=0;
            while(m--)
            {
                scanf("%d",&x);
                sum+=x;
            }
            printf("%d\n",sum);
        }

    return 0;
}

Java AC代码：

public class Main {

	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);

		int n = sc.nextInt();
		while(n-->0){
			int m = sc.nextInt();
			int sum = 0;
			while(m-->0){
				int x = sc.nextInt();
				sum += x;
			}
			System.out.println(sum);
		}
	}

}
