Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
Thanks for letting me know!! It should be fixed now.
I solve it changing the name of the function from mean to ExpandedForm!
I forgot to say, this problem come in java version.
There is a problem whit the SolutionTest!
When i click on "attempt" in output appear this:
/SolutionTest.java:10: error: cannot find symbol
assertEquals("2", Kata.expandedForm(2));
^
symbol: method expandedForm(int)
location: class Kata
....
