Quizplus · Accepted Answer

A deque is a data structure that allows insertion and removal of elements from both ends. It stands for the double-ended queue, and it can be implemented using arrays, linked lists, or other data structures. A deque is similar to a queue or a stack, but it allows efficient insertion or removal of elements from both ends instead of just one.
