Can you explain Dijkstra's algorithm?
Sure! Dijkstra's algorithm is a method for finding the shortest path between nodes in a graph, which can represent, for example, road networks.
How does it work step by step?
It starts by marking the initial node with a distance of zero and all other nodes with infinity. Then, it explores the nearest unvisited node, updating the distances to its neighbors.
What are some real-world applications of this algorithm?
It's widely used in GPS navigation systems, network routing protocols, and even in game development for pathfinding.
Are there any limitations to Dijkstra's algorithm?
Yes, it doesn't work well with negative weight edges and can be inefficient for very large graphs compared to other algorithms.
