--- Day 19: Monster Messages --- Part b: unsolved --- Day 21: Allergen Assessment --- No solutions.
--- Day 23: Crab Cups --- Part b: implemented my brutish j model in c, which ran 5 hours on a mainframe. Didn't bother to seek a pattern. --- Day 24: Lobby Layout --- Struggled with complex number comparisons until I thought to use integral coordinates. Struggled with memory overfill and slow performance until I had the insight that only the black tiles are required for the next day's tile pattern. I did not save my codes. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
