Ok, thanks. But how to fix it?

The tests have something like this ([1, 1, 1, 1, 1, 1, 1], 8) In this case, all cars will pass at once. Cars stand in line one after another.

Thank you, I will try to do it as soon as possible.

I think it will be useful to someone. You must return the result in the "get_pins" function and then there will be no error.
