This year I'm claiming a deduction on my taxes and doing the challenges in BQN. I have been very excited to try this language and I hope I do not fail miserably in rising to the challenge.
Everything's the same as last year. I'm changing the naming conventions of the files a little bit to make things less confusing. Files named 69.bqn and 69.in are the solution and input text respectively of the 69th day of the advent calendar. If a second part adds supplementary input text it'll be named 69.1.in or something like that.
