How does the performance of deque compare to other data structures?

How does the performance of deque compare to other data structures?

Deques, or double-ended queues, offer O(1) time complexity for insertions and deletions at both ends, making them efficient.

What about their performance compared to arrays?

Arrays have O(n) time complexity for insertions and deletions in the middle, while deques excel in these operations.

Are there specific use cases where deques are preferred?

Yes, deques are ideal for scenarios like implementing queues, stacks, and maintaining a sliding window for algorithms.

How do deques perform in terms of memory usage?

Deques typically use more memory than arrays due to their dynamic nature, but they provide greater flexibility.

Can you give an example of a programming language that supports deques?

Sure! Python has a built-in deque implementation in the collections module, which is widely used for its efficiency.
