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

#include<stdio.h>
int main()
{
    int m;
    scanf("%d",&m);
    for(int n=0; n<m; n++)
    {
        int j,i,a[100],s=0;
        scanf("%d",&i);
        for(j=0; j<i; j++)
            scanf("%d",&a[j]);
        for(j=0; j<i; j++)
        {
            s+=a[j];
        }
        if(n==m-1)
            printf("%d\n",s);
        else
            printf("%d\n\n",s);
    }
    return 0;
}
