Circular deques are a type of data structure that work better than regular deques in several important ways.
Using Space Wisely: Regular deques can waste space when there are empty spots because items are added and removed often. A circular deque solves this problem by making the array act like a circle. This means every available spot is used, even if it seems empty.
Speed of Operations: Both regular and circular deques let you add or remove items quickly—this is called time complexity. But, circular deques are faster because they don’t have to shift items around when they run out of space. This makes them more efficient when you're using them a lot.
Less Memory Use: Circular deques usually use memory more efficiently. When a regular deque needs to grow bigger, it can take more time because it has to get more memory. Circular deques can change size based on what you need without taking much time to find new memory.
Useful in Real-time Situations: Circular deques are especially good for tasks that need steady performance, like managing buffers for streaming data or scheduling tasks in systems that need quick responses.
In short, circular deques are designed to use space and time better. They fit well into real-world uses, making them a better choice than regular deques in many cases where the standard ones might have problems.
