The most complicated possible way of sorting a sentence by word length

sort_sentence

def sort_string(string)
  word_hash = {}
  new_word = ""
  string.split(" ").each do |word|
    word_hash[word] = word.length
  end
  numbers = word_hash.values.sort
  first_num = numbers.first
  new_word << word_hash.key(first_num)
  numbers.delete(first_num)
  numbers.each do |val|
    new_word << " " + word_hash.key(val)
  end
  new_word
end

def sort_string(string)
string.split(' ').sort{|x, y| x.length <=> y.length}.join(' ')
end
