We all played the other way round. Well done!

This is just so good! Pure maths to find out. I would never imagine such answer!!

Thanks to you I did "refactorise" (sorry, not my mother tongue!) my code. Appreciated!

Sure is long, I do agree with you. But I have to give to the person that wrote the solution that is robust as hell.

I got a problem at the end of the kata and I am a bit stuck at it. As I managed to get as a result an array with a solution that matches all of them (returns ['1000n','271n'] and so on and forth) I can't manage to get it as "gi" number (spolier's wise talking). Any tip to point me in the right direction? I feel like I am almost there, perhaps lacking a last step. I can provide code to whoever has got the right to answer me. Thanks for your time and patience.

I was working in a better approach from my previous solution. And the beggining of your function has been the particular importance. Thanks so much.

Gonna need sometime to process all this. bubble enters the nest...

Robust and clear: Upper and Lower covered. Curious, I feel like I am learning how to pilot airplanes but I have no idea how to drive a car. Something to think over.

I will try with regex, let's see if I can get it better.

I see the thought behind it. Just a new guy in here, but couldn't be use map/set key/values in here? I don't know, just a question.

Don't despair. Litle by litle. Took me a whole morning and part of the afternoon /evening. Then, found something I'd never saw before. Useful.

Holly Molly. Well done.
