Could you please explain to me how this works?

Very nice kata of the series to learn more about regular expressions.

Potential duplicate of Mod4 Regex

did I just write the single best one liner in a kata?? cant believe myself

Can someone explain what is happening here? Glitch in the matrix?

scarily creative.

I did not expect lambda itself, let alone that splicing technique.

Sexy

is it this type of floor as operation same as floor() funtion from the module Math? or it only serve for this purpose? example: you have 2.5 it only gives you 2 as a floor. then f you need to rount up or down then should be the time to use ceil and floor methods?

Solution so tiny I could tatoo it anywhere on my body. It wouldn't be readable when it's cold though.

I kneel!

There is a rule, "simple is better than complex".
It's due to is more simple do code inside of def function
rather than do a lambda function.

But it's definetly very clever solution :)

awesome
