Nice kata!

This was a fun one, thanks!

This was a fun one, thanks :)

Awesome, I wasn't aware that Array.from() takes a map function as the second argument. Will prove very handy in the future 🙏

I love how easy Ruby makes it to do things like this ❤️

I think this is more of a 7kyu :)

This was a fun one :)

Hey, thanks for giving a detailed explanation of your approach. I really appreciate it. I like your approach and think it's a good one.

I've also found over the years that it often helps to try and model my human thinking to code as much as possible. I too often forget this and try to write some beautiful and perfect solution the first time :)

Ooo, that looks interesting. Will be sure to give it a try next time :p

Hmm interesting, I'll give that a go, thanks.
I mostly create little tables as comments in my code and then see if a pattern emerges. It's amazing how our ape brains can do these things...

Curious to know how people go about solving katas like this. I just try and identify some sort of formula through trial and error.
I come up with a guess for a formula and test it with some inputs. I keep repeating until I hit something. This doesn't seem
very efficient but not sure how else to solve problems like this...

Hey,

Don't let just one kata discourage you. I've been programming professionally for six years and would find this Kata difficult. Not sure what type of programming you do but these kind of challenges aren't reflective of most day-to-day programming that most people do :)

Very nice!
