Looks like you need to actually read the challenge and not just skim it.

Hey,

I am new hear and I have to say that Code Wars is absolutely amazing. I am improving my knowledge of Java as I prepare to do an MSc in computer science, so this is probably the best tool for doing that out there.

However, Anton, I agree with you. There a re a lot of "replace this character in a string with this", or "group these together".

But for someone like me, in the lower ranks still, I guess it's not that bad.
