well i would advise to studdy Riemman Sums then, you'll understand where the code comes from ;)

WOW! very nice!

Daaaaaaaamn!

Maths! And it seems like I've gone into LINQ frenzy.

Very nice!

Use spoiler flag next time, please.

this code is awesome in optimization wise.

Use spoiler flag next time.

Wow!! This man must be a mathemagician

I agree, looking at this I can't really understand the math/algorithm behind this.
Especially as a beginner in programming this kind of solution is hard to read.

I like it when the gloves come off Voile, so now I'll be blunt too. You make an unfounded assertion that I didn't understand the original idea (presumably because it makes you feel all big and superior), and then you write arse-gravy about working code being maintainable by virtue of the fact that it works, kind of imply that it's perfectly fine for developers to write code without any thought for other people who may have to read it, state explicitly that good algorithms must necessarily equate to good code, and you strongly implied that the best solutions must always be highly optimised ones.

As I have said from the very beginning, and to spell it out for the hard of understanding, I LIKE THE SOLUTION but I wanted to make a wider point about professional code.

You can stay in your myopic world, where the lines of code are all that matter. I prefer developers with a bit of balance, a wider view and an ability to make the right compromises. Oh and I definitely prefer developers that have at least a minimal grasp of how to interact with other humans, a skill you are desperately lacking.

Fair enough. Picking your battles is also a key part of the review process ;)

Then you're just literally "bitching about things that are irrelevant", you know.

(I decided to use blunter words here because, well, comment section are supposed to inform people about the various advantages/disadvantages of a solution, not for people to write pages of rants complaining why they don't like a solution. Literally nobody gives a damn about that, so get over it and accept that you're salty and biased. Doesn't stop people doing this every day though)
