What are advanced queue operations in C++?

Advanced queue operations in C++ include priority queues, circular queues, and double-ended queues (deques). Would you like to know more about any specific type?

Can you explain how a priority queue works?

A priority queue is a data structure where each element has a priority. Elements with higher priority are served before those with lower priority. In C++, you can implement it using the STL's priority_queue.

How do I implement a circular queue?

To implement a circular queue, you can use an array and two pointers (front and rear) to keep track of the positions. When the rear reaches the end of the array, it wraps around to the beginning.

What are the advantages of using a deque?

Deques allow insertion and deletion from both ends, making them more flexible than regular queues. They are useful for implementing algorithms that require access to both ends of the data structure.
