Robust word compare algorithm.
Performance improvements.
How to play:
The goal of the game is to correctly guess the secret word which is of five letters without repeating letters. Once you enter your test word, the app announces how many letters match with the secret word. For example, if the secret word is BRAVE and the test word is BLACK, the matching letters are A and B, so the announced result is "2". Eventually you will have enough information to win by making a correct guess.
