Write a checkGuess() method so that it prints a message based on the String parameters, code and guess.
The message it prints will be decided as follows:
• If guess has exactly the same characters as code, then the message printed will be "Correct ".
• Otherwise, if the first character in guess is the same as the first character in code, the method should print "Same first letter".
• Otherwise, the method should print "Incorrect".
(Note: You may assume that both guess and code contain at least one character)
