I'm doing the Advent of Code and failed to spot the connection too. When I got to the day in question, I began to wonder why I was bothering. It was actually dead simple once I stopped trying to be clever. The key insight was that the input does NOT consist of numbers. (Part 1 was 18 lines of Smalltalk and part 2 was 25. I felt a bit sad at using so much code, but now that I *have* an APL system I find that my APL skills are rusty in the extreme.) Or was the key insight that the input is a matrix that you need to process by COLUMNS, not rows?
