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.

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.

nice one! you can make it even faster by creating a compile time multiplication table as i have done here, so all that happens at runtime is the bucketing of similarly aged fish, 7 multiplications + a sum

you've still got some overhead in your code, my rust solution creates a dense lookup array at runtime & takes ~200us on my 10850k. are you including file IO and printing to stdout?
