Description

In “Hangman Judge,” you are to write a program that judges a series of Hangman games. For each game, the answer to the puzzle is given as well as the guesses. Rules are the same as the classic game of hangman, and are given as follows:

1. The contestant tries to solve to puzzle by guessing one letter at a time.
2. Every time a guess is correct, all the characters in the word that match the guess will be “turned over.” For example, if your guess is ‘o’ and the word is “book”, then both ‘o’s in the solution will be counted as “solved”.
3. Every time a wrong guess is made, a stroke will be added to the drawing of a hangman, which needs 7 strokes to complete. Each unique wrong guess only counts against the contestant once.

   ______   
   |     |     
   |    O     
   |    /|\    
   |     |     
   |    / \    
   |___|_       
   |      |______
   |__________|
   

4. If the drawing of the hangman is completed before the contestant has successfully guessed all the characters of the word, the contestant loses.
5. If the contestant has guessed all the characters of the word before the drawing is complete, the contestant wins the game.
6. If the contestant does not guess enough letters to either win or lose, the contestant chickens out.

Your task as the “Hangman Judge” is to determine, for each game, whether the contestant wins, loses, or fails to finish a game.

Input Format

Your program will be given a series of inputs regarding the status of a game. All input will be in lower case. The first line of each section will contain a number to indicate which round of the game is being played; the next line will be the solution to the puzzle; the last line is a sequence of the guesses made by the contestant. A round number of ‘-1’ would indicate the end of all games (and input).## Output Format

The output of your program is to indicate which round of the game the contestant is currently playing as well as the result of the game. There are three possible results:

You win. You lose. You chickened out.

1
cheese
chese
2
cheese
abcdefg
3
cheese
abcdefgij
-1​

Round 1
You win.
Round 2
You chickened out.
Round 3
You lose.​

Hint

参考翻译： 猜单词游戏，单词中有数个字母。玩家需要猜对所有的字母。 玩家如果猜对一个字母，单词中的所有该字母都不用再猜了。猜对所有字母游戏获胜(You win.)。 玩家只有七次猜错的机会，第七次猜错时会失败（You lose.）。 如果玩家没有用完七次错误的机会，且没有猜对，则视为放弃（You chickened out.）。
