How to play:
Computer generates four non-repeated numbers
Press the number keys 0-9, after pressing send, the computer judges that the number position is correct as A, and the position is incorrect as B
For example: after inputting 1234, 1A1B is displayed
Indicates that one number is in the correct position, one is incorrect, and the other two are not guessed correctly
When 4A0B is displayed, it means all the guesses are correct. After the first number is sent, the timing will start
If it fails to guess 15 times, the challenge fails and the correct number is displayed.
Congratulations, click to start a new round to replay, or exit to exit the program.
Count the number of successes, the number of failures, the average number of successes, the average success time (seconds), and the average number of successes
