Where can I ask for an explanation about this answer to a Code Golf puzzle? I understand what the code does, but I just cannot figure out the logic/reasoning behind it, despite having read several articles about bitwise operations, checking if a number is a power of 2, etc. I know what a recursive function is. I just don't get why it has been used this way and why this works to answer to the puzzle.

  • I was going to ask a question in Code Golf, but as it's directly related to code, I then thought about posting it on SO. Hence this question. Also I didn't know there was a Code Golf specific meta, sorry about that. Aug 7, 2018 at 21:37

Seems like a textbook case for a comment to me:

When should I comment?

You should submit a comment if you want to:

On Codegolf Meta

If you ask there, you're more than likely to get a great explanation of how something has worked from the people who write the answers.

Provided they visit Meta of course.
