What are advanced priority queues in C++11?

Can you explain what an advanced priority queue is in C++11?

Sure! An advanced priority queue in C++11 typically refers to the use of the std::priority_queue class, which allows for efficient retrieval of the highest (or lowest) priority element.

How does the underlying data structure work?

The std::priority_queue is usually implemented as a max-heap, which is a complete binary tree where the value of each node is greater than or equal to the values of its children.

Can I customize the priority queue to use a different comparison?

Yes, you can customize the comparison by providing a custom comparator when you instantiate the priority queue, allowing for different sorting orders.

What are some use cases for advanced priority queues?

Use cases include scheduling tasks, managing event-driven simulations, and implementing algorithms like Dijkstra's for shortest paths.
