No, 6 is fine.

Thank you, nice Kata, I enjoyed it.

This Kata should be more then 6. At least 5. It was fun and challenging before I passed all the tests.

Too much code..

This is really best solution, no additional array needed and merging it back like the others do.

Nice Kata, if you go with Java then nice warm up for java Stream api...

This is sick :)

Nice Kata, just passed it in Golang, I'd rate it with 5 not 6.

For me, a golang learner, great kata, thanks

Fine Kata for Golang learner like me, but why 5Kyu? :)
Anyway thanks a lot :)

Just solved this Kata. Interesting, although this Kata is very nice recursive warmup,

basically all solutions are NOT recursive...:)

Very nice Kata, thank you :) No problem with tests.
