You are totally right. Plus, the timeout is due to an inappropriate choice of structure and not to the kata itself.

How would it be irrelevant? Your code is too slow, that's why it times out. Also please don't post twice for the same thing on a different thread. It's no use to flood the Discourse page because your code doesn't do what you would like.
