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

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