disc-loop / cows-and-bulls

An implementation the Cows and Bulls game. Written in Go for the purposes of learning the language.

Cows and bulls implementation.

Rules: A 4 digit sequence of numbers is generated. This will be called the "secret". The player must try to guess this sequence exactly within the fewest guesses possible. A digit in the guess can match a digit in the secret in two ways: 1) exactly, and 2) nearly.

• An exact match means that a digit in the guess is in the same place as that of the secret. e.g. Secret = 1423, Guess = 1099, Exact matches = 1 (the first digit of the guess matches the first digit of the secret)
• A near match means that a digit in the guess is present within the secret, but only if that digit has not already been near matched or isn't an exact match

TODO:

• Secret validation (correct length, valid characters)
• Consider menu implementation for looping (quit on key) and options (configure game, e.g. secret seed)
• Add config for secret length (configurable across the program)
• Secret generator (uses seed, or default)
• io for console(?)
• Dockerise app (lets us use ECS and expand the app)
