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

4 1 2 3 4
5 1 2 3 4 5
3 1 2 3

#include

int main()
{
    int m;
    scanf("%d",&m);	//  输入一个m表示有m组测试数据
    while(m--)       //  执行 n 次循环，进行n组测试
    {
        int n;
        scanf("%d",&n);         //  输入一个 n  表示这一组测试数据中有n个数
        int sum = 0;
        while(n--)             //  进行n次循环输入n个数
        {
            int a;
            scanf("%d",&a);
            sum += a;
        }
        if(m != 0)            // 如果不是最后一个数 则输出两个换行
        printf("%d\n\n",sum);
        else
        printf("%d\n",sum);   //  m 为 0 时是最后一组测试数据，输出一个换行就行
    }
    return 0;
}
