Sorry, Title should be problem 208

The example answer includes ZLA.

Should it also include ZLE, ZLI, ZLL & ZLZ?

Wow, it seems you are right and some nasty bug is here. I'm sorry and go see for it!

UPD I hope I've fixed the bug (?). I'm very sorry (Nicolas Patrois and Smwentum should be especially angry, I'm afraid, for they've tried this problem already). Strange thing that my lame solution passed tests at the course checker %)

Thank you very much, Graeme, for your help!
