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 you must note that there is a blank line between outputs.

Sample Input

3

4 1 2 3 4

5 1 2 3 4 5

3 1 2 3

Sample Output

10

15

6

#include <stdio.h>  int main(void)  
{  
    int n, m, a, sum, i, j;  
    scanf("%d", &n);  
    for(i = 0; i < n; i ++)  
    {  
        scanf("%d", &m);  
        sum = 0;  
        for(j = 0; j < m; j ++)  
        {  
            scanf("%d", &a);  
            sum = sum + a;  
        }  
        printf("%d\n", sum);  
        if(i != n - 1)        //這裏是這道題的重點              printf("\n");      
    }  
    return 0;  
}
