Looks cool but not optimal, so far I think it's O(n) the optimal solution.

This is not the best approach, since it has to go through the array three times.

Very neat!

thanks a ton marxsteal!! yes, definitely better late than never, outstanding reply, crystal clear now!!

I would just return Array.Empty(), since it's a singleton and does not take extra memory on creating a new array.

Briliant =)

amazing

So the compiler adds the value to the value? And that's faster than bitshifting? Huh, that's interesting.

It was faster at the beggining (like years ago) but now precesors are stronger and there is no point in doing it. You should not do it because it is easy to make mistakes and it is not clear enought.
