What are some advanced techniques for using a deque in Python?

You can use a deque for efficient appends and pops from both ends. Some advanced techniques include rotating the deque, using it as a queue or stack, and applying it in algorithms like breadth-first search.

How do I rotate a deque?

You can rotate a deque using the rotate(n) method, where n is the number of steps to rotate. Positive n rotates to the right, and negative n rotates to the left.

Can you give me an example of using a deque as a queue?

Sure! You can use append() to add items to the back and popleft() to remove items from the front, simulating a queue.

What are the performance benefits of using a deque?

Deques provide O(1) time complexity for append and pop operations from both ends, making them more efficient than lists for these operations.
