Thanks, but it's an illusion ;-).

"kata programming" is not a good place for real best practices:

• Have you seen nobody comments the code?
• All code is, usually, in one function

In general, the code I study here is all "write once, read it never". The code is not written to be maintainable. :-(

Nice style; I found that it can arrive there sometimes.

Preach

Maybe, but it is way more efficient that what I used to find these numbers.

does that count as cheating?
