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

題意概括：先輸入一個數N, 然後輸入N個數，讓N個數進行累加，輸出累加的和。如果輸入的N為0，結束。

AC程式碼：

import java.util.Scanner;
public class Main {
    public static void main(String[] args) {
        Scanner s = new Scanner(System.in);
        while(s.hasNextInt())
        {
            int n = s.nextInt(), sum = 0;
            if(n == 0)
            {
                break;
            }   
            for(int i = 1; i <= n; i ++)
            {
                int a = s.nextInt();
                sum += a;
            }
            System.out.println(sum);
        }
    }
}
