Deque: Meaning (information, definition, explanation, facts)

A deque, or double-ended queue is a data structure which unites the properties of a queue and a stack. Like the stack, items can be pushed into the deque; once inserted into the deque the last item pushed in may be extracted from one side (popped, as in a stack), and the first item pushed in may be pulled out of the other side (as in a queue).
