Building on your work in the previous section, you'll be storing each guessed letter in your already created table.
Modify your code such that each unique, valid guess that a player makes is stored in the 'letter' column in the 'guesses' table.
If a guess is made that is already stored in the database, this means that the player has already guessed that letter. The guess should not be counted as a valid guess and a message should be displayed to the player informing them that they have already made that guess and should guess again.
Note:
Keep in mind that case shouldn't matter; a guess 'a' should be seen as being the same as a guess 'A'
