Mikey is playing with his favorite toy blocks, each depicting one letter of the alphabet. He is trying to make words using all his blocks, but as he does not know valid words from invalid ones, he goes by all possible orderings of the letters in alphabetical order and asks Albert, his genius brother, if the word he made is a valid one. Mikey can make one word (including asking a question and getting an answer) every sixty seconds, and he never makes the same word twice.
Albert is delighted about Mikey's activity, but would rather not teach Mikey certain words. Help Albert by predicting when Mikey will start making a certain forbidden word, so he can set the alarm clock indicating Mikey's bedtime to just before this moment.
