Indeed. It's a pretty common trick when you have to cycle through some smaller array using the indices from a larger one.

Ya, I know. That comment was really just me quibbling with myself over the semantics of 'best practices' and the educational utility of an easy kata.

You're my codewars idol, btw ;-)

Excellent kata!

Thanks for writing these. I enjoy simple kata for easing into a new language. They help one push through the initial tedium of term memorization.

If you look at the top of the kata, you will see that it says, "Postgresql 9.6" or something similar. That tells you the specific version of SQL being used for this kata. Search online for the appropriate function to use for postgresql. It's similar to hex().

I wrote this function for decoding bitfield messages in the BitTorrent Peer Wire Protocol. The spec uses this order.

I find it interesting that most of the solutions are string-based...

nice solution. mine was similar

This is a nice kata :)

I didn't know boolean expressions behaved this way. Very clever solution!
