I practiced a similar question where clearing a container affected the size. I feel like the output might be option A, but I can't recall exactly.

I remember something about queues and how they manage their size. I think `third.size()` should return 10, but I'm confused about `mylist.size()` after clearing it.

I think the program should compile fine since all the includes are correct, but I'm not sure about the output.
