I do not know what I should do. I have not decided this kata, but I think it's super :D

Excellent kata, decided with pleasure ))

Yes. But I can not figure out what needs to change. I used round and BigDecimal, but that does not work.

Hi! Help me find a mistake, I know that the error in the rounding, but do not know where. Testing is successful, but "SUBMIT" no.

This shift one letter?

Thanks for the answer! Now it is clear.

For a description of the problem and the examples it is not clear under what set of letters will be mistakes. Tell me in detail an error in what cases? Thank you!

Hi! Who can explain why there is such an error? I have rows with no such numbers in the code ...
/GreetMeTests.java:11: error: non-static method greet(String) cannot be referenced from a static context
assertEquals(GreetMe.greet("riley"), "Hello Riley!");
^
/GreetMeTests.java:15: error: non-static method greet(String) cannot be referenced from a static context
assertEquals(GreetMe.greet("BILLY"), "Hello Billy!");
...

Necessary checks to Null?

At this task there are a lot of decisions what after all will be correct?

I have this problem too.How to solve it?
