What are some applications of deques in C++?

Deques, or double-ended queues, are versatile data structures in C++. They allow insertion and deletion from both ends, making them useful for various applications.

Can you give me some specific examples?

Sure! Deques are often used in scenarios like implementing queues, managing buffers, and in algorithms that require frequent addition and removal of elements from both ends.

How do deques compare to vectors in C++?

Deques provide faster insertions and deletions at both ends compared to vectors, which are optimized for random access but slower for these operations.

Are there any performance considerations I should be aware of?

Yes, while deques are efficient for adding/removing elements, they may have slightly higher memory overhead compared to vectors due to their dynamic nature.
