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.

Nice warming kata, thank you.

Thanks guys. I already cracked this Kata. Btw I noticed someone down-voted my original question...Why..? :(

This Kata should be 7Kyu not 5.

Just solved this Kata. I think it should be 5 Kyu imho.
