    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
     
    -----------------------------------------

     1 #include <iostream>
     2 using namespace std;
     3 int main()
     4 {
     5     int m,n,a,s;
     6     cin >> m;
     7     for (int i=1;i<=m;i++)
     8     {
     9         cin >> n;
    10         s=0;
    11         for (int j=1;j<=n;j++)
    12         {
    13             cin >> a;
    14             s+=a;
    15         }
    16         if (i!=m)
    17         cout << s << endl << endl;
    18         else
    19         cout << s << endl;
    20     }
    21     return 0;
    22 }
