Is there any way to to see/visualize the input tree? Its hard to know what Im doing wrong if I don't really know what the tree looks like.

try printing your inputs for the fixed and random tests.

I pass when I run the sample tests, but when I hit attempt I get an indexError which makes no sense. It works fine when I run it in Pycharm with the array that gave me an indexError here. My code also produces correct results when I run all of the tests found in the instructions in Pycharm.

Interesting Kata. Thank u dude.
