How does a deque work?

Can you explain how a deque works?

Sure! A deque, or double-ended queue, allows insertion and deletion of elements from both ends.

What are the main operations I can perform on a deque?

The main operations include adding elements to the front or back, removing elements from either end, and accessing elements.

Can you give me an example of when to use a deque?

Absolutely! Deques are useful in scenarios like implementing a queue for breadth-first search in graphs.

How does a deque differ from a regular queue?

A regular queue allows insertion at the back and removal from the front, while a deque allows both operations at either end.
