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

#include<stdio.h>
int main()
{
    int n,a,b,i,sum;
    scanf("%d",&n);
    for(i=1;i<=n;i++){
        scanf("%d",&a);
        sum=0;
        while(a--){
            scanf("%d",&b);
            sum+=b;
        }
        if(i==1) printf("%d\n",sum);
        else printf("\n%d\n",sum);
    }
    return 0;
