​​A+B for Input-Output Practice (VIII​​)

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

import java.util.Scanner;
public class Main {
  public static void main(String[] args) {
    Scanner sc=new Scanner(System.in);
    int n=sc.nextInt();
    boolean boo=true;
    while(n-->0){
      int m=sc.nextInt();
      int sum=0;      
      for(int i=0;i<m;i++){
        int a=sc.nextInt();
        sum+=a;
      }
      if(boo){
        boo=false;
      }else{
        System.out.println();
      }
      System.out.println(sum);
    }
  }
