I'm not sure, but I think there might be a compilation error in line III.

Hmm, I'm pretty sure there won't be any compilation errors in this code. It looks like a straightforward queue manipulation exercise to me.

Haha, this question is a real head-scratcher. I bet the instructor is just trying to trick us with some obscure C++ syntax we've never seen before.

Wait, are we allowed to use `queue>` and `queue>` in C++? I thought only the default `queue` was available.

The program should output 10 11 12 10 11 12, as it creates two queues, one with a vector and one with a list, and then prints the elements of both queues.
