一个简单的智力游戏，游戏者每次只能猜一个字母，如果游戏者猜的字母在单词中，单词中所有的该字母将被视为已猜出，例如：如果原单词是apple，游戏者猜出了p，则程序应显示当前猜出的残缺单词为-pp--；设置选择时间限制或猜错次数限制，超过限制则游戏失败。(In a simple puzzle game, the player can guess only one letter at a time. If the player guesses the letter in the word, all the letters in the word are considered to have been guessed. For example, if the original word is apple, the player Guess the p, then the program should display the current guess the word for the missing-pp--; set the choice of time limit or guess the number of times the limit is exceeded, the game fails.)
