Number guessing (also known as BullsandCows) is an ancient puzzle game, which originated in the mid-20th century and is usually played by two or more people, or by one person and a computer.
Usually two people play, one gives the numbers and the other guesses. The person who gives the number must come up with a four-digit number, and the number cannot be repeated, and the guesser cannot know it. Those who can guess can start guessing. Every time you guess a number, the molecule will give several A's and B's according to this number, where the number before A indicates the number of correctly positioned numbers, and the number before B indicates the number of correctly positioned numbers. You can also ask questions in a homophonic way and then answer the numbers in Chinese characters.
