Hold on, I think the answer is B. There's got to be a compilation error in line I, right? You can't use a vector with a queue like that.

Haha, this code is a real brain-teaser! I'm going to have to think this one through carefully.

I believe there won't be any compilation errors, the program should run smoothly

Wait, I think there might be a problem with line I. Shouldn't we be using a deque instead of a vector for the fifth queue?
