For some reason this solution is very slow for big arrays.

Could be the most efficient approach... :>

Yeah, I think a history or "older version" beneath (or expanded from) the current one would be a lot easier to work with than duplicates that look near identicle to one another.

Am I correct in saying that the \1 and \2 sub in the first and second mathes?

BTW, I used re.sub("(?<=.)(?=[A-Z])","_",str(string)).lower() as shown here: http://www.codewars.com/kata/reviews/5463c85a372ca866430000d4/groups/55ba30c61f97ea5c82000061 for my Regex.

I have updated the description. Hope it is clearer now.

It took me a while to notice you were talking about the left of the vector not just the left of the line drawn out by the vector.

@bkaes I don't mind them being up I refactored a solution and made very minor changes (adding a space in the right place) but the old one is still there. It seems silly to have two answers that are almost idential to not exist as one answer. Maybe there should ab a history for refactored solutions.

If you "unlock solutions" for a kata in another language you can then create a translation in the desired language without having to solve it.

The question is about removing a solution. This 'refactor' action does not remove old solution, it just adds a new, refactored one, and leaves the old one published as well.

Click on "link". It will bring you to a page that only shows that specific solution. You should be able to comment there.

You can refactor them, which is kind of cumbersome. You need to search look through all your solutions, find the right one, and click on "refactor".

That being said, keep in mind that you gave the CW people an irrevocable licence to publish your content/solution. If the content isn't actually yours to publish, contact them by mail or similar.

You can't.

How can I remove solutions that I have submitted?
