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

Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;

class Main {
  public static void main(String[] args) {
    Scanner stdInt = new Scanner(System.in);

  int j = 0;
  int[] ans = new int[1000];

    while (true) {
      String x;
      x = stdInt.next();
      int tmp=0;
      for (int i = 0; i < x.length(); i++) {
        tmp += x.charAt(i) - '0';
      }
      if (tmp == 0) break;
      ans[j++] = tmp;
    }

    for (int i = 0; i < j; i++) {
      System.out.println(ans[i]);
    }
  }
}
