Sure! A common example is in scheduling tasks where some tasks are more urgent than others, like in operating systems.

What data structures can I use to implement a priority queue?

You can implement a priority queue using binary heaps, Fibonacci heaps, or even simple linked lists, depending on your needs.

Are there any downsides to using priority queues?

Yes, priority queues can have overhead in terms of complexity and performance, especially if not implemented efficiently.
