At the break of an English class, a382050365 and Power were so bored that decided to play a word puzzle to kill time.
This game follows the following rules:
1> They in turn say a word containing only vowel (A, E, I, O, U)and the next word being said should exactly begin with the same letter as the last letter of the former word.
2> It can starts with only a single word.
3> Each word can be said only once and must be contained in the dictionary.
4> The total length all the word used in the game is defined as the complexity of the game. Tian found it’s hard to end the game in a short time. So he had a question .What’s the max
complexity of the game based on a certain dictionary.
