Yes, you are right. I was hasty and submitted too early :(

Thanks for your contribution. I would suggest adding a few simple tests for users to work with prior to submission.

Thanks for the heads up!

Yes, I was a little surprised that it passed all the tests.

Good point. The one-liner "best practice" might be sub-optimal in terms of asymptotic complexity. I think yours is O(n): O(n) (for split) + O(n) for the explicit loop. So the whole thing is still O(n). But the one-liner might be O(n**2) given the way min() is used.

I agree. This exercise seemed much easier than other 4kyu kata.
