Sorry, I made a mistake.I will delete this comment. Nice kata. Thank you

I don't see why that would be an issue. You're the one causing it not to compile, yes? So, write something that does compile instead. It's not like the kata is preventing you from writing compiling code, is it?

error in tests for Go:

codewarrior/kata_test [codewarrior/kata.test]

./kata_test.go:38:24: cannot use n (variable of type uint) as int value in argument to CountBits

you should initialize the result like this result := make([]int, 0)
