A simple CL program that counts cards and advises on whether to hit or not in a game of 十點半.

Usage

The program keeps track of a deck and your hand. There are two modes

• Hit Mode: card codes result in the corresponding card being added to the hand and removed from the deck
• Normal Mode: card codes result in the corresponding card being removed from the deck only While in Hit Mode, the program will advise you on whether to hit or not when a new card is added to the deck. Normal Mode is used to keep the deck up to date when cards are dealt to other players.

The program uses a distribution monad to model the probabilistic computation following Oleg Kiselyov's lecture at FLOLAC'16.
