Title: Guess the word game, the rules are as follows:

1. The guessing person guesses one letter at a time;

2. Every time the quiz is correct, all the characters in the word are guessed correctly;

3. Guess the wrong guesses 7 times, then the guessing person loses; the same character counts only one error;

4. The guessing person guesses all the characters, then the guessing person wins. If you have not won or lose the quiz, then the guessing person give up;

  sample Input   
 1  
 cheese  
 chese  
 Span style= "FONT-SIZE:13PX;" >2  
 cheese  
 ABCDEFG  
 3  
 cheese  
 abcdefgij  
 -1 
  
  sample Output   
 round 1  
 you win.  
 round 2  
 you chickened out.  
 round 3  
 you lose.  

Idea: Because all the inputs are lowercase letters, use an array of AA to record the characters that appear in the guessing word. And then traverse the guessing of the sequence, if aa[s[i]-' a ']=1, then guessed, otherwise there is no guess, the number of records did not guess count, if count>=7 the guessing loser;

If Count<7 and aa[i]!=0 exist, the guessing person will give up the game. If the count<7 and AA array values are 0, the guessing winner wins.
