How to implement a stack using queuqe

[jkmyoung]

In general, it's a pretty bad idea.
There's a couple avenues you could take. Did you want to use a double queue option to implement the stack?

Or are you talking Singly Linked List? That would make a lot more sense.

What do you mean by queue?

As abstract software engineering terms, a stack is a last-in-first-out (LIFO) structure, while a queue is a first-in-first-out (FIFO) structure. These are fundamentally incompatible. However, actual implementations of stacks and/or queues sometimes sacrifice conceptual purity for flexibility that might be used to breach the incompatibility .
