it's the convex side of the parentheses isn't seperated by whitespace

this is a codewars issue.

Thanks for the info and doc unfortunatly the tests are generated on codewars end so I do not have access to fix that.

Should be solved now.

Thanks for your feedback. This is the problem with the built-in compare_with helper. Hopefully it'll be fixed soon.

Thanks, and good luck! :)

Java version is ok. Check the error message you've posted, do you see what's missing?
