What are some advanced usage techniques for C++ deques?

C++ deques are versatile! You can use them for efficient insertions and deletions at both ends. What specific techniques are you interested in?

Can you explain how to use deques for a sliding window algorithm?

Sure! A sliding window algorithm can be efficiently implemented using a deque to maintain the current window's elements. You can add elements to the back and remove from the front as the window slides.

What about using deques for priority queues?

While deques aren't priority queues by default, you can implement one by maintaining a sorted order when inserting elements. This way, you can efficiently access the highest priority element.

Are there any performance considerations I should be aware of?

Yes, while deques provide constant time insertions and deletions at both ends, random access is slower than vectors. Consider your use case!
