Dijkstra Algorithm Questions
The visited set in the Dijkstra Algorithm is significant because it keeps track of the vertices that have been explored and their corresponding shortest path distances from the source vertex. This set helps in ensuring that each vertex is visited only once and prevents revisiting already explored vertices, which helps in finding the shortest path efficiently. Additionally, the visited set allows the algorithm to determine when all the vertices have been explored, indicating that the shortest path from the source to all other vertices has been found.
