What are the performance characteristics of deque operations?

What are the performance characteristics of deque operations?

Deque operations, like insertions and deletions, are generally O(1) for both ends, making them efficient.

How does a deque compare to a stack or queue in terms of performance?

A deque allows insertion and deletion from both ends in O(1) time, while stacks and queues are limited to one end.

Are there any specific use cases where a deque is preferred over other data structures?

Yes, deques are ideal for scenarios like implementing sliding window algorithms or when you need to manage elements from both ends.

What programming languages have built-in support for deques?

Languages like Python, C++, and Java have built-in support for deques, often through libraries or standard templates.
