Less lines != good code

class Even
  def even(n)
    n.even?
  end
end

A bit tounge in check, but I love Ruby too for things like this.

I loved it.

Brilliant!

Not as many mod 10s ;-)

It is what?

Yes, it is

Thank you,
I realized my code didn't even check for multiple y's so it would have failed that test anyway.

then fork it

i'm pretty sure you could just do

bool IsOdd(int x) {return !(x % 2 == 0);}

It should include a case with "yyyyaaaasss" for good measure. Currently, the single Y part does not show up in the test cases.

How do I make randomized tests?

This can probably be improved. My solution is sloppy.

Ok, thank you.
