//Introduction
// Your task is to sort a given string. Each word in the string will contain a single number. This number is the position the word should have in the result.
// Note: Numbers can be from 1 to 9. So 1 will be the first word (not 0).
// If the input string is empty, return an empty string. The words in the input String will only contain valid consecutive numbers.

//Examples
// "is2 Thi1s T4est 3a"  -->  "Thi1s is2 3a T4est"
// "4of Fo1r pe6ople g3ood th5e the2"  -->  "Fo1r the2 g3ood 4of th5e pe6ople"
// ""  -->  ""

//The best Practices
function order(words){
  return words.split(' ').sort(function(a, b){
      return a.match(/\d/) - b.match(/\d/);
   }).join(' ');
}  

//Others
function order(words){
  if (words.length == 0){return words}
  let wordsarr = words.split(' ');
  let indarr = words.match(/\d/g);
  let neword = [];
  for (let i=1;i<=indarr.length;i++){
    let ind = indarr.indexOf(i.toString())
    neword.push(wordsarr[ind])
  }
  return neword.join(' ')
}
