WebMar 18, 2024 · In this tutorial, we have discussed the Dijkstra’s algorithm. We use this algorithm to find the shortest path from the root node to the other nodes in the graph or a tree. We usually implement Dijkstra’s algorithm using a Priority queue as we have to … 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.
