北京大學ACM比賽題
The game of Scrabble is played with Tiles. A tile either has a single letter written on it, or it is blank. In the latter case, the tile may be used to represent a letter of your choice. On your turn, you arrange the Tiles to form a word. Each tile may be used at most once, but not all Tiles need to be used. Given several Scrabble Tiles and a dictionary, determine how many words in the dictionary can be formed using the given Scrabble Tiles.
