Shouldn't it be tested that the function is indeed a lambda/closure/... ?

Hello,

Could you please check and approve the Java Translation (https://www.codewars.com/kumite/62124fda1d5475001661ee49?sel=62124fda1d5475001661ee49) of the kata.

Thanks

A Regular Expressions tag would be appropiate.

Description is unclear and allows totally dissimilar implementations. Are we supposed to write a class method, a function? I have solved this kata with no problem in several language, but I'm not very competent in Ruby and I have no idea what I'm supposed to do in this language.

Ruby 3.0 should be enabled.

Ruby 3.0 should be enabled.

Initial code template similar to JS and C# should be used for all languages. Not sure if this should be labelled as an 'issue', so just suggestion for now.

There are self-interacting polygons in the test cases, which don't have a well-defined orientation. Quoting from Wikipedia:

For a self-intersecting polygon (complex polygon) (or for any self-intersecting curve) there is no natural notion of the "interior", hence the orientation is not defined

In fact the author solution and most of the existing solutions can return either orientation depending on the shape (but not the topology) of the self-intersection polygon.
