Good work Adrian, but, I'm scratching my head, because it seems to me that
you missed the one sequence that represents the original puzzle.
Contestant chooses door. Host chooses a nonprize door from the unchosen
two. Contestant switches from his first choice to the other unrevealed
door.

Am I missing something?
