MODERATORS
Wow, that is very fast, nice. I was happy with 120ms, seems I'm leaving a lot of performance on the table.
Edit: Regex cut my total time in half, but I am measuring the whole execution, still a massive improvement.
The 3ms are for part 1 only, part 2 takes around 27ms. But I see that our approaches there are very similar. One difference that might make an impact is that you copy the substrings for inserting into the hashmap into
Strings.Removing the string copy with the length->count array from @sjmulder saved me 20ms, so not super significant. I'll have to play the the profiler and see what I am doing wrong.
I think your approach looks a lot more Rust-like, which I like. Part 1 in 4 lines is very nice.
