It seems hard to solve, quite intuitive.

start_hour will never be equal to end_hour now.

Thanks for reporting this issue to our attention, closing.

now_hour = 18
start_hour = 18
end_hour = 18
It should work for random inputs too: True should equal False

However,

I will allow Vasya to play at least one hour a day.

either don't generate these cases, or fix the reference solution.

Approved

python new test framework + random tests are required. updated in this fork

I was just thinking about how to use the binary tree to find the solution and this is exactly what I'm looking for.

closing then ;-)

Sorry. I found the mistake in my code. Not an issue.

can you provide more details ? what is the input, what is the expected answer, what is the answer which you think is correct ?

In Python the fist fixed test on the attempt part has 11 spaces in the right answer instead of 10 spaces
