As well as my Day 4 solutions in Python and Java, I talk about the AI solving controversy in Advent of Code, and teach the chat bot to speak a language I just now invented.
I did this puzzle last night while writing the post about Day 2. This time I’m not in quite so much of a rush. Weekends….
I am committing myself this year to solving every puzzle in the Advent of Code, an annual coding competition taking place over the Advent season…
