Most hangman implementations I have seen keep a list of characters the player has already guessed and compares them to the players current guess each time to see if they have already made the same guess. My implementation checks if the word was changed after replacing any matches. Is my implementation easier to understand as well as more efficient than this one Hangman game logicistics and cleanliness?
Side Question: Should I use static variables in loops?
