On day 8 Advent of Code 2021 adventure, part 1 lulled me into a false sense of security. It took longer to read the instructions than implementing the code. But then part 2 was back with a vengeance. Admittedly it would have been so much easier if I slowed down a bit and actually counted carefully. As it happened it was a good reminder that “more haste, less speed” applies to programming very much.
