For future readers Collections.sort(..,Collections.reverseOrder());

I just added that the matrix is quadratic. Thanks for the suggestion!

I agree.
Unless the list is immutable, which I am afraid that we could not guarantee merely from the description of the Kata.

thank you! :)

Glad you enjoyed it! :)

You are absolutely right! I think, I written this from instinct :D

Clearly the tests need to be updated then. Wonder if the author of the kata will see this soon.

That sounds like a good idea. the course is ending soon and it sounded like the next time around oracle might set up their own auto-validating homework system.

Thanks :) Although now that I'm looking at it again, it could use a tiny bit of refactoring.

I don't know if I can delete the kata and republish a new and what about the 800 guys who passed?

You can wait till #163 is fixed and apply the obsolete solution tactic I mentioned in #123.
