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.

 输入包含一个整数N在第一行，然后N行。每一行的开始都有一个整数M和M个整数，然后在同一行。

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.

 对于每一组输入整数，你应该在一条线和输出，你必须注意在输出之间的空白行。

#include<iostream>

using namespace std;
int main()
{
	                int n, m;
			int k;

			while (cin >> k)
			{

				while (k--)
				{
					
					cin >> n;
					int sum = 0;
					while (n--)
					{
						cin >> m;
						sum += m;
					}
					if (k > 0)
					{
						cout << sum << endl << endl;
					}
					else
					{
						cout << sum << endl;
					}
				}

	return 0;
