cargo-aoc VS AdventOfCode2021

I’ve never used it but I’ve seen people talk about cargo-aoc for this: https://github.com/gobanos/cargo-aoc

I've been using rust the last few years and decided to go back to clojure. I had been using https://github.com/gobanos/cargo-aoc with my rust solutions and really liked having the functionality from the framework when solving the puzzles each day.

I use https://github.com/gobanos/cargo-aoc which is based on Criterion.rs. The measured time does not include parsing.

Recently I’ve been doing it in rust using cargo-aoc

Now, for rust, there is cargo-aoc which minimizes friction to a great extend.

Note also that you can solve this without a complexity dependency on n. Most solutions I have seen, including mine run in time O(tD), where t is the maximum value of a timer, and D the number of generation, requiring O(t) memory. (This is assuming we can do the required arithmetic operations in constant time, and each numbers require a fixed around of memory storage; if the number of fish gets huge, throw in an additional log n in the complexities, where n is the number of fish on the final day).

Based on my matrix exponentiation solution, here is a closed-form solution:

In my Perl solution of today (I assume, you mean 2021, Day 4), I read stuff in paragraph mode ($/ = "") which makes Perl split input on 2 or more newlines.

I considered doing that for my (Perl) solution, but given the cards are small, that seemed overkill.
