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

using namespace std;
int n,ans;
int main(){
    scanf("%d",&n);
    for(int i=1;i<=n;i++){
        int m;scanf("%d",&m);
        for(int j=1;j<=m;j++){
            int x;scanf("%d",&x);
            ans+=x;
        }
        if(i<n)    cout<<ans<<endl<<endl;
        else cout<<ans<<endl;ans=0;
    }
