Questions & Step-by-Step Solutions

What is the initial value of the tentative distance for the source node in Dijkstra's algorithm?
  • Step 1: Understand that Dijkstra's algorithm is used to find the shortest path in a graph.
  • Step 2: Identify the source node, which is the starting point of the path.
  • Step 3: Set the tentative distance for the source node to 0 because it is the starting point.
  • Step 4: Remember that all other nodes will have their tentative distances set to infinity at the beginning.
