Is the Distinct() necessary? Also the x < n? (Not criticizing just asking to understand this better)

This one confused me, im sure there is a reasonable explantion, but just looking at it, i'd assume it wouldnt work

I farted

WOW

Can someone explain "DataTable", please???

Please fork from this translation to fix this. Rejecting current translation.

This needs to be updated to NUnit3 Assert.That style.

Didn't even know Linq could be used like that (°ロ°)!

I like this!

Я этого чара родственник!

Please take time to check documentation of a function before using it : IsLetter() match more chars than a-z and A-Z

It is very concise, but at least I have to think harder to verify correctness. I'd like to optimize for readability with minimal congnitive load. I can imagine people that could parse this this without any cognitive load... probably the author. :)

Crafty! (Though if I saw this in a C# code review we would need to have a little talk.* :D ...though I know that in some languages, massive chains of ternaries are the norm.)

*Edit: Actually, it might be fairly readable if formatted with some line breaks.

Horribly slow, would be a major chore to maintain. Why Linq? KISS
