Finally yesss I finished it!!, I am beginner less than a month in C# and about 1 year on-off learn coding. For this kata my way of solution maybe like "reverse engineering" methode. I am not cleaning up messy comment in my solutin for remainder to my self.

Very nice , learning so many things.

I've just finished this kata using C#. I am still beginner so it took days to finished:), took many small steps to understand it because majority time I did it on side monitor while playing game on the main monitor.

Passed basic and several random test.
Remaining several random test failed.
I think I have the clue "prioritize the caller on other floor if its same direction with previous direction",
"queue of the current floor not always granted to enter although the lift is empty"
But still confuse how to implement this clue. Using python, took many hours with my level of coding but still not solved :)

In the instruction it should able to handle sets. But I see top solution don't include sets as argument, how they passed?. My solution is able to handel lists and sets.
