What is deque explain?
A deque, also known as a double-ended queue, is an ordered collection of items similar to the queue. It has two ends, a front and a rear, and the items remain positioned in the collection. In a sense, this hybrid linear structure provides all the capabilities of stacks and queues in a single data structure.
What is deque used for?
