aoc VS Play2022

I compared this to my python code (https://github.com/mattbillenstein/aoc/blob/main/2016/05/p.py) - running it with pypy3 (3.8.13): 8.5s; your C solution here runs in about 7s (gcc -O3). Python3 (3.10.6) 18.4s. I thought the C code would be much faster.

Here's my solution for this one: https://github.com/mattbillenstein/aoc/blob/main/2021/16/p.py

Kotlin.

I'd recommend looking at other people's Kotlin code. Mine would be OK except that I use too many custom library calls. I recommend Todd Ginsberg's Kotlin solutions blog. He's very thorough in his discussion.

Here you go.

My submission code had the dubious distinction of working on the first try, but it was a tangled nightmare of when statements and bad ideas kludged on top of other bad ideas.

Kotlin

It's very useful to be able to benchmark with some kind of timer. I wrote a Stopwatch class for this purpose, but subtracting from System.nanoTime is easy and is the perfect thing to put in a template so you never have to deal with the boilerplate again.
