• There should be more random tests (~ 100). Random tests shold always cover both valid and invalid (no path) cases.
• Returning different types (list/bool) is bad practice. When there isn't a path the function shopuld return a "no-value" (None in python) or raise an exception.

The assertion messages should provide information about what was wrong (see the docs).

As dfhwze noted, this isn't likely to be approved, but it's good to know for another kata.

Hi, this is my first authured Kata so my might be a few bugs here and there. Feel free to leave a message and I will respond as soon as possible.

is this a depth first approach?

Cool stuff! You should add a hero as well.

I love how there are so many different ways to approach one problem!

Very concise solution!

mhm, alright...

Operator overloading.

Guess it's a good thing the author didn't throw large lists in for testing.

Going to the comments section was the best decision I made in a long time ;)

loving the input validation :)

I get it :)
