Advent of Code 2024 Day 3 (BaseA Style)

Day 3 in the bag! Worth mentioning that I upgraded to 24.2 in the middle of Part 2, just so I could use the new expression editor with the multi-row formula tool! It was SO much better...

Okay, I have a bone to pick with this one . . . I knew my method was solid and couldn't figure out why it wasn't working until I noticed . . .

Spoiler

. . . the first mul() commands are NOT preceded by a do()!!!!!!!

I think this is cheap and incorrect. Fight me.

Brain didnt want to regex today, so while there is a lil bit here mainly just workarounds

The dos and don'ts were a tad tricky.

I took a long way round - going to go back and have a look at some of the pure regex solutions like @clmc9601

Part 1- just a simple regex to parse this out. First regex finds the multiplier and the second breaks it into X and Y

Part 2 - I couldn't get this working in regex alone - so I did something different:
- add don't()do() at the beginning
- Split the string by don't() - this means that every string is excluded until you see a Do
- Then split by do()
- Discard the first split before the first do and the rest are useful strings (anything before the first Do is covered by a Don;t
- then apply part 1

And here is the python for today - quite a few fun list bits - I may go back and use an accumulator just for kicks.

as always - full solutions are here: SeanAdams10/AdventOfCodePython: Advent of code challenges in Python - across multiple years

Tool golf was fun after wrapping my head around it. Starting to get festive.

With that I just say..... Welcome to Advent of Code. Better get over it now because I assure you there are tons more where that came from! Great work overcoming the challenge!
