too easy :clown:

Maybe to make sure the input is always a boolean

why?

Yeah, but the description clearly says "first character will be the desired answer" so while your approach is more correct (or best practice) and solves wider problem, the task itself was much simpler in this case.

Closing as it's too late to make corresponding changes

how

Still O(n). Of course, saving max and min results will make it twice faster.

There's random tests in C++, you must have select wrong language

Disabled 3.6.

It's probably a kata bug.

Make sure that you have selected Python 3.8 and not Python 3.6 and try again.

Please use a spoiler flag. It would be harder. Most of currently posted solutions use it and this would make senseless the majority of votes to rank the kata. This kata is now a bit old and has been solved many times, so in case it would be approved with te change you propose, its rank would not match its actual difficulty.
