How can I use deques in C++ effectively?

Deques, or double-ended queues, allow insertion and deletion from both ends. What specific operations are you interested in?

I want to know how to implement a deque from scratch.

You can implement a deque using a dynamic array or a linked list. Would you like a code example for one of these methods?

Yes, please provide a code example using a linked list.

Here's a simple implementation of a deque using a doubly linked list. Would you like to see how to use it in a program?

Absolutely! Show me how to use the deque in a sample program.

Here's a sample program that demonstrates adding and removing elements from both ends of the deque. Let me know if you need further explanations!
