I really enjoyed this kata, it's been a fun exercise in functional programming for me. Thanks a lot!

thanks, I didn't know!

In camel case the first word is lowercase. https://www.freecodecamp.org/news/snake-case-vs-camel-case-vs-pascal-case-vs-kebab-case-whats-the-difference/

But excuse me, is this normal? s='G' => ' G' In my opinion the function should return 'G'
Similarly 'GrDn' => ' Gr Dn' but it should be: 'GrDn' => 'Gr Dn'

It's strange that this solution passed all the tests
