input: Write a python function to classify words based on their length.
  assert classify_words(["code", "data", "text", "test"]) == (["code", "data", "text", "test"], [])
  assert classify_words(["a", "ab", "abc", "abcd"]) == (["abcd"], ["a", "ab", "abc"])
  assert classify_words(["hello", "world", "hi", "bye"]) == (["hello", "world"], ["hi", "bye"])
output: def classify_words(words):
      max_length = max(len(word) for word in words)
      longest_words = [word for word in words if len(word) == max_length]
      other_words = [word for word in words if len(word) != max_length]
      return (longest_words, other_words)
