I add have to dissent that opinion. Just because people solved the problem doesn't mean it isn't extremely difficult to read. I went and ahead and skiped this kata exactly because of this reason. It's just too much bad translation for me to decipher the text to work the problem. Not worth the time. As far as feedback I'd say remove the all the story from the actual problem needing be solved.

Thanks for the feedback. Actually, I'm not english mother tongue; so, maybe, the description can be improved, it can be fair: have you any specific advice?
Apart from that, more than 130 people in this community have solved this (relatively) easy kata without giving to me this feeling. In my opinion, this is not the point.

In this community, as we gain experience with several katas we feel the need to step up our code skills. I looked at your solution and, frankly speaking, I am pretty sure you don't really understood the truly essence of this kata: that is the point. I hope this kata(and his description), at least, helped you think.

The language is English, but poorly translated. There are issues with grammar usage which make it more difficult to understand the problem.
