This appears to be fixed.

And I just solved this kata in Java - found out that it doesn't support Java only when I tried to submit my solution. Well, I've learnt my lesson - always check supported languages before starting work on a kata.

Ouch! Thanks for pointing that out. I've corrected that test and reduced the threshold to the correct value of 2 (as per http://en.wikipedia.org/wiki/Mandelbrot_set).

Thank you very much, Pablo, for doing this job. Translations are good! :)

Edit: Now it covers. Should return the lowest missing number.

Fixed. Thanks!

Thanks Pablo, that's a really great feedback.

The reason why I did not include a link to the wikipedia page, is because the actual page is very dry, and not really informative.

I think it would be worth updating the wikipedia page before providing the link, that is something I might do once I have more spare time.

For now if you know any good resourses on the topic, please let me know and I'll include them.

Thanks againg for the awesome feedback.

Fixed.
Thanks for the feedback!

Well, it says in the problem description that the test strings will only contain those symbols. Actually, when I first started writing this, I considered that, but I thought it would just be a needless addition that distracts from the actual problem - a quick two line for loop or one line regex removes that element altogether, so I thought it didn't really add anything to the problem.
