input: Write a function to find sequences of similar strings in a given text using difflib.SequenceMatcher.
  assert find_similar_sequences("this is a string with a few similar words") == ["this", "is", "a", "string", "with", "a", "few", "similar", "words"]
  assert find_similar_sequences("hello world hello") == ["hello", "world", "hello"]
  assert find_similar_sequences("python code python code") == ["python", "code", "python", "code"]
output: def find_similar_sequences(text):
      import difflib
      
      words = text.split()
      sequences = []
      
      for i, word in enumerate(words):
          if i == 0 or not difflib.SequenceMatcher(None, words[i], words[i-1]).ratio() > 0.6:
              sequences.append(word)
