What is a double-ended queue?

A double-ended queue, or deque, is a data structure that allows insertion and deletion of elements from both ends.

Can you give me an example of how it works?

Sure! In a deque, you can add elements to the front or back. For instance, you can add 'A' to the front and 'B' to the back.

What are the advantages of using a double-ended queue?

Deques provide flexibility in data handling, allowing efficient operations at both ends, which can be useful in various algorithms.

How does it differ from a regular queue?

Unlike a regular queue, which only allows insertion at the back and deletion at the front, a deque allows both operations at either end.
