What are some use cases of deque in data science?

Deque, or double-ended queue, is useful in data science for tasks like managing data streams, implementing sliding window algorithms, and optimizing data retrieval.

Can you explain how deque is used in sliding window algorithms?

Sure! In sliding window algorithms, a deque helps maintain the current window of elements efficiently, allowing for quick access and removal of elements as the window slides.

Are there any specific libraries in Python that support deque?

Yes, Python's collections module provides a deque implementation, which is optimized for fast appends and pops from both ends.

What are the performance benefits of using deque over a list?

Deque offers O(1) time complexity for append and pop operations from both ends, while lists have O(n) for these operations, making deque more efficient for certain tasks.
