yeah men, the problem was my code well not, the problem was my logic in that moment, but I can do it the challengue.
The problem was that I misunderstand the assert section.
thanks for the help

thanks for the help guys, I don't think about the version node, and I will thinking again my code.

I do not know what happens with the tests, when I perform my function it does it in the correct way in the way it is in the instructions, but it tells me that it expects another value and it is the sentence with repeat cheracteres.
What happen?
