Can you explain what a priority queue algorithm is?
A priority queue algorithm is a data structure where each element has a priority. Elements with higher priority are processed before those with lower priority.
What are some common examples of priority queue algorithms?
Some common examples include Dijkstra's algorithm for shortest paths, A* search algorithm, and Huffman coding for data compression.
How does Dijkstra's algorithm use a priority queue?
Dijkstra's algorithm uses a priority queue to efficiently select the next vertex with the smallest tentative distance during the search.
Can you give me a real-world application of priority queues?
Sure! Priority queues are used in scheduling tasks in operating systems, where processes with higher priority are executed first.
