How do priority queues differ from regular queues?

How do priority queues differ from regular queues?

Priority queues and regular queues both store elements, but priority queues allow elements to be processed based on priority rather than just the order they were added.

Can you give me an example of where I would use a priority queue?

Sure! A common example is in task scheduling, where tasks with higher priority need to be executed before lower priority ones.

What are the main operations for both types of queues?

For regular queues, the main operations are enqueue (adding an item) and dequeue (removing an item). For priority queues, you also have enqueue, but the dequeue operation removes the item with the highest priority.

Are there any specific data structures used to implement priority queues?

Yes, priority queues are often implemented using binary heaps, but they can also be implemented with other structures like balanced trees or unordered lists.
