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 Scala (judge verdict: Accepted)

object SumOfNumbers {
  val sc = new java.util.Scanner(System.in)


  def run {
    var l = sc.nextLine()
    while (l != "0") {
      println(sum(l))
      l = sc.nextLine()
    }
  }
  def sum(line:String): Int = {
    val a =line.toCharArray

    val b = a.map( n => n.asDigit)

    b.sum

  }

}


object Main extends App{
 SumOfNumbers.run
}
