overload )) I thought the fork was removed ))

So, you fork a Kumite titled "...without converting to string", and put a string conversion in the code..

Perhaps fork one of the ones that have done this predictable, inefficient approach to death..

You don't really need number of digits for this; you can just repeatedly divide the input number by 10 on each loop until it hits zero (or mods to 3)

Hey! I wanted to give some feedback on the Kata.

At first glance, I was think what do these letters represent ('n', 's', 'w', 'e') and only after reading it again it was clear that they are cardinals.
It might be easier/faster to understand when the letters become cardinals ('north', 'south', 'west', 'east').

I hope my feedback will be useful!
