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

 

解题思路：把两道题结合了下。

代码如下：

#include <stdio.h>
int main()
{
    int a, z, s, n;
    int i, sum;
    scanf_s("%d", &s);
   
        for (z = 0; z < s; z++)
        {
            scanf_s("%d", &n);
            sum = 0;
            for (i = 0; i < n; i++)
            {
                scanf_s("%d", &a);
                sum += a;
            }
            printf("%d\n", sum);
            if (z < s-1)
                printf("\n");
            else
                break;

        }
   
    return 0;
}
