it's now year's end. i consider the aoc challenge over. in total 18/25 challenges were completed. 2d-grid navigation and other responsibilities suspended my progress. i will continue to churn out solutions to this year's puzzles and prior year's puzzles through the end of next year.

I just completed "Restroom Redoubt" - Day 14. #AdventOfCode

I completed "Garden Groups" - Day 12. Part 2 was beyond my scope. #AdventOfCode

"Plutonian Pebbles" - Day 11 - Advent of Code 2024 completed! #AdventOfCode adventofcode.com/2024/day/11
