What are some use cases for deque in Python?

Deque, or double-ended queue, is useful for scenarios like implementing queues, stacks, and maintaining a sliding window.

Can you give me an example of using deque for a sliding window?

Sure! You can use deque to efficiently manage the elements in a sliding window for problems like finding the maximum in a subarray.

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

Deque provides O(1) time complexity for appending and popping from both ends, while lists can be O(n) for these operations.

Are there any limitations to using deque?

One limitation is that deque may use more memory than lists due to its underlying data structure, especially for small datasets.
