What is the output of Dijkstra's algorithm if the graph is disconnected?

Step 1: Understand that Dijkstra's algorithm is used to find the shortest path from a starting node to other nodes in a graph.
Step 2: Recognize that a disconnected graph means some nodes cannot be reached from the starting node.
Step 3: When Dijkstra's algorithm runs, it will calculate the shortest paths to all nodes that are reachable from the starting node.
Step 4: For nodes that are not reachable (because the graph is disconnected), Dijkstra's algorithm will indicate that the distance to these nodes is infinite.
Step 5: The final output will show the shortest paths to reachable nodes and infinite distance for unreachable nodes.
