Question: What is the initial value assigned to the tentative distance of the source node in Dijkstra\'s algorithm?

Options:

  1. Infinity
  2. Zero
  3. One
  4. Negative infinity

Correct Answer: Zero

Solution: 

The tentative distance of the source node is initialized to zero, as it is the starting point of the path.

Questions & Step-by-Step Solutions

What is the initial value assigned to the tentative distance of the source node in Dijkstra's algorithm?
  • Step 1: Understand that Dijkstra's algorithm is used to find the shortest path from a starting point (source node) to other nodes in a graph.
  • Step 2: Identify the source node, which is the starting point of the path.
  • Step 3: Assign a value to the tentative distance of the source node. Since it is the starting point, the distance to itself is zero.
  • Step 4: Conclude that the initial value assigned to the tentative distance of the source node is zero.
