Normally it’s somewhat tedious to generate the squares of a chess board that can be attacked by bishops or nights, but we make short work of it using comprehensions to generate and filter the board positions down to the solution. We also reach to Erlang to fill in a gap in Elixir’s logical operator tool set.

The Square module was from Lesson 8 and the challenge was from Lesson 10 of Alchemist Camp.
