Solution in JavaScript (judge verdict: Wrong Answer)

'use strict';
(function(stdin) { 
  var inputs = stdin.toString();
  (function(array) {
    console.log(array.sort(function(a,b){
        return a - b;
    }).join(' '));
  }(inputs.split('\n')[0].split(' ').map(Number))); 
}(require('fs').readFileSync('/dev/stdin', 'utf8')));
