The goal is to write an API for the tic-tac-toe game. An API user, should be able to play a game of tic-tac-toe using this API, but importantly, it should be impossible for the API user to break the rules of the game. Specifically, if an attempt is made to break a rule, the API should reject the program. This is often done by way of a compile-time type error.

The following API functions should exist:

• move: takes a tic-tac-toe board and position and moves to that position (if not occupied) returning a new board. This function can only be called on a board that is empty or in-play. Calling move on a game board that is finished is a compile-time type error.

• whoWon: takes a tic-tac-toe board and returns the player that won the game (or none if neither has won). This function can only be called on a board that is finished. Calling whoWon on a game board that is empty or in-play is a compile-time type error.

• playerAt: takes a tic-tac-toe board and position and returns the (possible) player at a given posi
