Questions & Step-by-Step Solutions

What is the output of Dijkstra's algorithm if the graph has multiple shortest paths?
  • Step 1: Understand that Dijkstra's algorithm is used to find the shortest path in a graph.
  • Step 2: Recognize that a graph can have multiple paths that are equally short between two points.
  • Step 3: When Dijkstra's algorithm runs, it explores paths and keeps track of the shortest distance to each point.
  • Step 4: If there are multiple paths with the same shortest distance, Dijkstra's algorithm will choose one of them based on its internal logic.
  • Step 5: The output will be one of the shortest paths, but it won't show all possible shortest paths.
