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

答案：

#include
#include
int main()
{
        int x,i,j,n;
        scanf("%d",&x);


        for(j=0;j         {
        scanf("%d",&n);
         int s=0,a[n];


        for(i=1;i<=n;i++)
        scanf("%d",&a[i]);


        for(i=1;i<=n;i++)
        s=s+a[i];
        printf("%d\n",s);
        if (j != x-1)printf("\n");
        }
  return 0;
