Welcome everyone to the 2023 advent of code! Thank you all for stopping by and participating in it in programming.dev whether youre new to the event or doing it again.

This is an unofficial community for the event as no official spot exists on lemmy but ill be running it as best I can with Sigmatics modding as well. Ill be running a solution megathread every day where you can share solutions with other participants to compare your answers and to see the things other people come up with

Day 1: Trebuchet?!

Megathread guidelines

Keep top level comments as only solutions, if you want to say something other than a solution put it in a new post. (replies to comments can be whatever)
Code block support is not fully rolled out yet but likely will be in the middle of the event. Try to share solutions as both code blocks and using something such as https://topaz.github.io/paste/ or pastebin (code blocks to future proof it for when 0.19 comes out and since code blocks currently function in some apps and some instances as well if they are running a 0.19 beta)

Part-A in Python: https://github.com/pbui/advent-of-code-2023/blob/master/day01/day01-A.py

Was able to use a list comprehension to read the input.

Part-B in Python: https://github.com/pbui/advent-of-code-2023/blob/master/day01/day01-B.py

This was trickier...

Hint

You have to account for overlapping words such as: eightwo. This actually simplifies things as you just need to go letter by letter and check if it is a digit or one of the words.

Update: Modified Part 2 to be more functional again by using a map before I filter

Re. your hint, that's funny because I skipped the obvious optimization of skipping over matched letters out of laziness, but it would've actually broken the solution.
