Problem Description

Your task is to Calculate the sum of some integers.

 

Input

Input contains multiple test cases. Each test case
contains a integer N, and then N integers follow in the same line. A test case
starting with 0 terminates the input and this test case is not to be
processed.

 

Output

For each group of input integers you should output
their sum in one line, and with one line of output for each line in input.

 

Sample Input

4 1 2 3 4

5 1 2 3 4 5
0

 

Sample Output

10

15

 

 

import java.util.Scanner;

public class Acm20190416 {
    public static void main(String[] args)
    {
        Scanner input=new Scanner(System.in);
        while(input.hasNext())
        {
            int n=input.nextInt();
            if(n==0) break;
            else
            {
                int[] a=new int[n];
                for(int i=0;i<n;i++)
                {
                    a[i]=input.nextInt();
                }
                int sum=0;
                for(int j=0;j<a.length;j++)
                {
                    sum+=a[j];
                }
                System.out.println(sum);
            }

        }
    }
