Yeah, I should've expected part 2 to have a ridiculous amount of fish... I went with a HashMap for saving how many fishes were at ages 0-8 each day. These are my favourite types of exercises, simple code and the solution is not immediately apparent. Cleanest code yet! GitHub

Thought today's solution looked pretty clean. Regex for parsing the input, a HashMap for saving overlaps and a simple .scan() for generating the points.

Kotlin solution (part 1 and part 2 merged)

Kotlin solution, probably not the most efficient but does the job.

Kotlin solution for day 7, can be done fairly concisely:

Kotlin solution using a fish counter map:

Day 3 — a few key concepts used are: extensions for example on List type higher-order functions aka a function which takes other functions as parameters

Nice! here is my solution also in Kotlin

Kotlin solution for day 3, not the most concise nor most optimized but gets the job done and fairly readable.

Kotlin, solution for part 1 and 2 — not super concise but a few cool concepts if you're learning the language.

You can find the source code for my solution here.
