Programming

The Day 03 challenge involves the calculating whether a character symbol is adjacent to a part number in a two dimensional map, such as:

467..114..
...*......
..35..633.
......#...
617*......
.....+.58.
..592.....
......755.
...$.*....
.664.598..

and then doing things with the part numbers.

After refreshing my knowledge of the rust parsing library ’nom’ with the day01 challenge, I was keen to do the second challenge without, simply using the standard library’s string manipulation and default parsing for this simpler parsing problem.

It’s been quite some time since I’ve taken time to enjoy coding challenges primarily for the fun of it. Over the next months, I’m keen to work my way through the 2023 Advent of Code - a fun set of problems created by Eric Wastl strung together with a seasonal story - and write up a bit about my own learning and fun.
