Problem solution in Python 2 programming.

#!/bin/python

import sys

def toInteger(s):
    try:
        print int(s)
    except Exception, e:
        print "Bad String"

S = raw_input().strip()
toInteger(S)


Problem solution in Python 3 programming.

Problem solution in Javascript programming.

process.stdin.resume();
process.stdin.setEncoding('ascii');

var input_stdin = "";
var input_stdin_array = "";
var input_currentline = 0;

process.stdin.on('data', function (data) {
    input_stdin += data;
});

process.stdin.on('end', function () {
    input_stdin_array = input_stdin.split("\n");
    main();    
});

function readLine() {
    return input_stdin_array[input_currentline++];
}

/////////////// ignore above this line ////////////////////

function main() {
    var S = readLine();
    
    try {
        var num = parseInt(S) || error;
        console.log(num);
        
    } 
    catch (error) {
        console.log("Bad String");
    }
