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?

SIMILARITY BETWEEN QUEUE AND STACK : The Stack and Queue both are the Non-primitive data structures. Stack and queue is linear data structures they both stores sequentially. Insertion and Deletion operation can be performed on Stack as well as in 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.
