What is the time complexity of priority queues?

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 is the best use case for a priority queue?

Priority queues are ideal for scenarios like scheduling tasks, managing bandwidth in networks, or implementing Dijkstra's algorithm for shortest paths.

Can you explain how a binary heap works?

A binary heap is a complete binary tree where each node is smaller (min-heap) or larger (max-heap) than its children, ensuring efficient access to the highest or lowest priority element.
