wise word

Thanks, I will

Try this kata?

ok, I'm becoming a true believer. I see a pattern of the highest rankings going to the solutions that can do it in one line, which is not a valid measure for value of the code. It often leads to the most maintainable code, but rarely to the most efficient solution. In this case I profiles my solution against this solution and found this solution to be 33% faster.

I remain skeptical, especially of the solutions relying on multiple string conversions, but I applaud this solution.

This is a very efficient solution. The only change I would recommend is to use n&1 instead of suffering the cost of a division for n%2
