WebDijkstra's algorithm is used to find the shortest distance between the nodes of a graph. We can use this algorithm for both directed and undirected graphs, but it won't work with negative edge weights. We can further optimize our implementation by using a min-heap or a priority queue to find the closest node. ← Java Type Casting.
