How does a beginner go about understanding this regex? I can follow the parenthesis and understand the asterisks, but it's difficult to grasp the logic behind searching for the given sets of 0s and 1s. I can't even understand how to normally solve this kata without a regex, so I feel bad for getting stuck on this 4 kyu when I've completed others at this difficulty level.

Can you explain what has happened here ?

how did I not think of that. Apparently at 2 a.m. the brains don't really work. xD

Is there any limitation on the number of horses with same leg size?

What's the upper limit of N? (C#)

This is a fine non-recursive solution. There is however some duplication in the methods that can be removed.

• ###### Sasha Markovcommented on "Concurrent task execution" csharp solution

Absolutely forgot about it. The use of `UnionWith` will be slightly more effective (especially on large collections). Thanks! :-)

Thanks for solving my kata! I just noticed onet thing in your solution and wanted to give you a small hint: `ISet` has a method called `UnionWith` which is pretty much equivalent to `AddRange` for lists. I think it was made distinct for sets because they do not necessarily operate on ranges per se. Cheers!
