Problem:
Sum of Numbers

Write a program which reads an integer and prints sum of its digits.

Input

The input consists of multiple datasets. For each dataset, an integer x is given in a line. The number of digits in x does not exceed 1000.

The input ends with a line including single zero. Your program should not process for this terminal symbol.

Output

For each dataset, print the sum of digits in x.

Sample Input

123
55
1000
0

Sample Output

6
10
1

Solution in JAVA (judge verdict: Runtime Error)

import java.util.Arrays;
import java.util.Scanner;
public class Main {
	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		int sum = 0;
		int a = 0;
		int i = 0;
		while (true) {
			int abc = sc.nextInt();
			if (abc == 0) {
				break;
			} else {
				String data = String.valueOf(abc);
				String[] result = new String[data.length()];
				
					for (i = 0; i <= data.length() - 1; i++) {
						result[i] = String.valueOf(data.charAt(i));
						a = Integer.parseInt(result[i]);
						sum = sum + a;
					}

					System.out.println(sum);
					sum = 0;
				}
			
		}
	}
