The Nineteenth Byte

Python 2, 68 bytes def x(n):r=range(-n,n+1);print sum(a*a+b*b==n for a in r for b in r) Defines a function called x() that takes a number n. As far as I know, this is allowed by default. Try it online. http://ideone.com/aRoxGF

@VoteToClose The thing is, the problem is simple and doesn't lend itself to much variation in approaches. Anyone who saw it would have trivially arrived at the same answer as Mego's. I thought the fact that I spotted a non-trivial optimisation justified my submission.

@Mego To clarify: There's no rule that you have to suggest improvements to other answers or that you cannot post highly similar ones. That's just a personal choice.

@xsot ¯\_(ツ)_/¯ Very well. However, 2 bytes is bound to make someone rage at you in the future. ;) Maybe next time, pointing it out instead might be more popular. c:

Anonymous

@xsot You took literally the same approach to the main part of the problem, but rearranged the code so that it was shorter. That is a trivial optimization. A non-trivial optimization would be finding a way to do the main task in a significantly different way (such as calling a different function from time or a different module).

Q: Why can't I post my answer after others use my language?

I've been getting a lot of grief lately about posting Python answers after other users have already posted a Python answer. Not only do I come up with these independently, they sometimes are shorter/different solutions. I'm getting really tired of this. Sources: http://chat.stackexchange.com/tr...

That's an entirely different discussion. The Doctor's answer were longer than the pre-existing answers in the same language.

AH-HA! Got down to 23 bytes @VoteToClose!

Maltysen

If it counts for anything, my vote is that this was a pretty clever optimization, and deserved a separate answer.

Dennis

@Mego All content you post on SE gets a CC-BY-SA license, so even if somebody takes your code, golfs off a byte and posts it, he doesn't violate any rule, as long as he provides attribution. That doesn't mean the answer shouldn't be downvoted into oblivion; I'm just nitpicking on the word rule.

My perspective on this is "why are you all making such a fuss?". Specifically, @Mego, you still have more upvotes on your answer than he does, and xsot did make a fairly clever optimization.

The issue here is, I cannot golf my answer further without it being a direct copy of his, because he took my answer and golfed it further, initiating what became essentially a golfing arms race, despite my answer being posted 2 hours prior to his. So now I'm stuck with an unoptimally golfed answer that would typically be deleted by the author in favor of a more-golfed answer using the same approach, despite posting first.
