HDU 1096 A+B for Input-Output Practice (VIII)

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

题意：输入n，代表n组数据，每组数据输入m及m个数，求m个数的和

注意：两组数据之间输出一个空行

#include <stdio.h>
int main()
{
    int n, sum, m, i, a;
    while (scanf ("%d", &n)!=EOF)
    {
        while(n--)
        {
        scanf ("%d", &m);
        sum = 0;
        for (i=1;i<=m;i++)
        {
            scanf ("%d", &a);
            sum += a;
        }
        printf ("%d\n", sum);
        if(n != 0) printf("\n");
        }
    }
    return 0;
}
