import java.util.Scanner;

public class Main {
public static void main(String args[]) {
    Scanner reader = new Scanner(System.in);
   int a,b,c,d;
    c = reader.nextInt();
    while(c>0)
    {
    d = reader.nextInt();
    b=0;
    while(d>0){
    a = reader.nextInt();
    b += a;
    d--;
    }
    System.out.println(b);
    System.out.println();
    c--;
    }
    reader.close();
