This is a simple web-based guess the number trivia game.
The game is played by guessing a 4-digit number without zero and duplicate digits. For each guess, the game will return the number of correct digits in the correct position (A) and the number of correct digits in the wrong position (B).
For example, if the answer is 1234 and the guess is 1356, the game will return 1A1B. Because 1 is in the correct position and 3 is in the wrong position.
