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 JavaScript (judge verdict: WA: Presentation Error)

"use strict";

function Main(stdin) {
    stdin=stdin.split("\n");
    var sum=0;
    for(var i=0;sum=0,i<stdin.length;i++){
        stdin[i].split(" ");
        if(stdin[i][0] === "0")
            break;
        for(var o=0;o<stdin[i].length;o++){
            sum+=parseInt(stdin[i][o]);
        }
        console.log(sum+"\n");
    }
}
    
function debug(){
	var input = document.getElementById("input").value;
	Main(input);
}

Main(require("fs").readFileSync("/dev/stdin", "utf8"));
