Questions & Step-by-Step Solutions

What is the main application of Dijkstra's algorithm in real-world scenarios?
  • Step 1: Understand that Dijkstra's algorithm is a method used to find the shortest path in a graph.
  • Step 2: Recognize that a graph can represent various things, like cities connected by roads.
  • Step 3: Identify that GPS systems use maps that can be represented as graphs.
  • Step 4: Realize that when you want to go from one place to another, the GPS needs to find the quickest route.
  • Step 5: Conclude that Dijkstra's algorithm helps the GPS calculate the shortest path between your starting location and your destination.
