Agreed, line I is fine.

Louisa 10 days ago

I think line I is correct. Simple initialization.

Suzan 15 days ago

Yes, those look correct to me.

Tasia 20 days ago

So, A, B, D, and E?

Lettie 25 days ago

True, line V is good. All options are valid.

Cyril 1 month ago

Line V is also valid. Vector works well.

Suzan 1 month ago

I feel line IV is correct. It’s valid syntax.

Tasia 1 month ago

Line IV is tricky. List as a container?

Lettie 2 months ago

Line II is good, but what about line IV?

Cyril 2 months ago

Line II seems fine too. Using deque is okay.

Suzan 2 months ago

Agreed, line I is definitely valid.

Tasia 2 months ago

I think line I is correct. Simple initialization.

Terrilyn 2 months ago

I thought stacks could only use specific containers, not just any!

Raul 2 months ago

Line IV is correct, but Line V seems off to me.

Stevie 3 months ago

Wait, can you really initialize a stack with a deque?

Lashanda 3 months ago

I think Line II is valid too!

Golda 3 months ago

Line I is definitely correct.

Paola 3 months ago

I practiced a similar question, and I think line IV is valid since it uses a list as the underlying container for the stack.

Laurel 3 months ago

Line II seems tricky; I feel like it should work, but I can't recall if stacks can be directly initialized with a deque.

Maile 3 months ago

I think line I is definitely correct since it’s just a basic stack initialization.

Lea 4 months ago

I remember that stacks can be initialized with different containers, but I'm not sure if all these initializations are valid.
