What is the time complexity of priority queues?
The time complexity of priority queues depends on the underlying data structure. For example, using a binary heap, insertion and deletion operations have a time complexity of O(log n).
Are there other data structures that can be used for priority queues?
Yes, priority queues can also be implemented using Fibonacci heaps, which offer better amortized time complexities for some operations, like decrease-key.
What are the advantages of using a Fibonacci heap over a binary heap?
Fibonacci heaps provide better amortized time complexities for operations like decrease-key and merge, making them more efficient for certain applications.
Can you give me an example of where priority queues are used?
Priority queues are commonly used in algorithms like Dijkstra's for shortest path finding, as well as in scheduling tasks in operating systems.
