I believe there might be a compilation error due to incorrect usage of insert function

I'm not sure, but I think the program will output: 0 1 2 3 4 5 6 7 8 9

I agree with Casie, because the code inserts 10 at the beginning of d1

Haha, this question is like a deque of trouble! I'll say option D, compilation error. Who knows what kind of shenanigans the compiler might pull with all these containers and iterators?

Yeah, the code looks fine to me. It should work without any compilation errors.

I'm a bit unsure about this one. I'll go with option A, the program outputs 0 1 2 3 4 5 6 7 8 9 10. Inserting an element at the end of the deque seems like the straightforward approach.

Hmm, this seems like a tricky one. I'm going to go with option B, the program outputs 10 0 1 2 3 4 5 6 7 8 9. Inserting an element at the end of the deque using the reverse iterator makes sense to me.
