AdventOfCode-Java VS AoC

Java Today was very easy, but it took me considerable effort to wrap my mind around the problem. I was almost about to do a multithreaded solution when I facepalmed and implemented what I actually had to implement.

Java Fun day, I like space cards. I had minor Vietnam flashbacks to the spacecards of last year, but luckily it was nothing like that. Some takeaways:

Check mine https://github.com/Fadi88/AoC/blob/master/2021/day19/main.rs Just checking orientation invariant property to get matching sensors and form there calucte rotation

check my solution

python incomplete

i would like to think that my code is a bit readable (i hope)

rust

feel free to check my code

rust ported from python

wow , just finished mine, not feeling so well about it, it tripled in size not being able to do comprehension in rust and having to explicitly specify every data tpye :/ https://github.com/Fadi88/AoC/blob/master/2021/day19/main.rs this gets around 1.4 second in release mode on the same machine

My math solution brute force velocity pairs but check for only 4 or 5 point max per pair and in python takes 40ms for part 2 code

python modeling the equations was the way to go no need to loop over all time steps to get the en position, just using equations of motion
