While queue and stack aren’t wildly different in performance, they obviously induce a different node-visiting order. One of them may give a more cache-friendly order than the other, depending on how your nodes are laid out in memory.
What is the similarity between stack and queue?

What is a stack example?
A stack is an Abstract Data Type (ADT), commonly used in most programming languages. It is named stack as it behaves like a real-world stack, for example – a deck of cards or a pile of plates, etc. For example, we can place or remove a card or plate from the top of the stack only.
