🚪 Deque

This page provides links to solutions that use the Deque approach.

Overview

A deque (double-ended queue) is a linear data structure that allows insertion and deletion of elements from both ends, front and back. It's more flexible than a regular queue or stack, making it efficient for scenarios that require operations at both ends.

How to Spot These Problems

You can identify deque problems if the problem requires you to:

• Efficiently access, insert, or remove elements from both the front and the back of a sequence.
