Got a bit lucky that my part 1 solution went into part 2 really well. Still need to get better at grid manipulation in general (and build out my helper methods), but not a bad showing.

A remarkably easy day for this late into the event. The main key is realizing how much duplication occurs and caching it. I really thought part 2 would be something about each towel growing in length to be honest If you are interested in AoC content in blog form, I recently posted my thoughts on days 11-15, viewable here: abnew123.substack.com/p/advent-of-code-2024-part-3, and will post all day...

Very chill day for this late into Advent of Code. Glad to have a breather, I thought for sure part 2 was going to involve moving while the bytes were falling from the air in real time or something.

I think this is the first day where brute force fails (at least, given a naive algorithm for running the program). Took a bit of thinking to see how to split up the second part into manageable chunks.

Extremely long day for me. I would honestly not recommending watching more than the first ten minutes, but posting the full thing for completeness. Problem viewable at adventofcode.com/2024/day/16 Solution file viewable at: github.com/abnew123/aoc2024/blob/main/src/solutions/Day16.java

3 day streak of at least one part being top 1000! Very poor assumption on my part though to assume each additional row of boxes being pushed is necessarily a superset of the previous row.

Lots of small, common paper cuts today between being off by one on checks, being unsure on x vs y, and correctly getting the positive modulo of a number. Overall relatively smooth though, it's the first ascii art in a while If you are interested in my blog, that's viewable here: abnew123.substack.com/p/advent-of-code-2024-part-1 Problem viewable at adventofcode.com/2024/day/14 Solution file vie...

Unfortunately one of my worst part 2 ranks today, just a single calculation being flipped had huge consequences. Annoying because two negative multiplied become a positive, it had no impact on part 1, but I suspect the numbers get too big for part 2 that a Java long cannot hold them. Maybe I should use something like BigInteger going forward, but there's a lot of nice things you get with using ...

Tough day. It really took me a very long time to think of how to calculate the number of sides for part 2, but I'm glad I eventually figured it out.

Apologies for not uploading yesterday, the video was unfortunately stuck for some reason on the initial OBS recording screen. If you are really interested, I did publish it as unlisted here: ua-cam.com/video/xntv0OJmnUI/v-deo.html but again, it's basically just audio.

Well, definitely a tougher day, but also just an insanely poor showing by me. At least we're likely to get an easier question tomorrow. Also, watching back over it, I definitely hallucinate my example output being wrong. For some reason I thought the correct answer was 2854 and my solution was 2858 the first time (when it was actually vice versa) Problem viewable at adventofcode.com/2024/day/9 ...

More commentary. First time my custom Utils library actually helped, and as a result, my first day getting within top 500 on both parts. Really hope I can break top 100 on at least one day this year.

First talking day, hope the volume is alright. Also, let me know if you are interested in my prep for each day, or if you know a better way to do the concatenate operation.

Forgot to add the initial guard location, unfortunate that the example has the guard returning to the initial square so it doesn't matter Problem viewable at adventofcode.com/2024/day/6 Solution file viewable at: github.com/abnew123/aoc2024/blob/main/src/solutions/Day06.java
