What is the performance of deques in C++?

What is the performance of deques in C++?

Deques in C++ offer average O(1) time complexity for insertions and deletions at both ends, making them efficient.

How do deques compare to vectors in terms of performance?

Deques are generally better for frequent insertions and deletions at both ends, while vectors are faster for random access.

Are there any specific use cases where I should prefer deques over vectors?

Yes, use deques when you need to frequently add or remove elements from both ends, like in a queue or double-ended queue.

What about memory usage? Are deques more memory-intensive than vectors?

Deques can be more memory-intensive due to their non-contiguous storage, while vectors use contiguous memory, which can be more efficient.
