And what is relevant reaction on such "bad" data? Should I throw an exeption or should I jast handle that with some specific answer?

I tryed to solve this with Java. And for void string, correct string array and array with only 1 element it is passed. But there are 3 more tests under submittion. Is there any chances to reveal the code of that tests or we should relay on our luck only?

Hi!
Does anybody know what we should return in case where the format of inputed strings are not meet the conditions? For example: if the inputed string is just " 20" and we return 20 it fails. As well as if we return "", null or (20). So what should it be?

Thanks! You're right, I didn't consider that possibility.

Guys, I'd finally reached an impasse: I can't get throw the 7th test of submiting. Does anybody know what kind of sequence it has as an input for Java vercion of kata?
