Answers

1
A node is considered fully processed in Dijkstra's Algorithm once the shortest distance to it has been confirmed.
True
False
2
Which of the following conditions must the graph meet for Dijkstra's Algorithm to work correctly?
The graph must be a tree
The graph must be acyclic

3
How does Dijkstra's Algorithm handle unvisited nodes?
It processes them immediately after the start node

It assumes their distance is infinity until updated
It treats them as having a distance of zero
4
In Dijkstra's Algorithm, what is the purpose of the priority queue?
To store the nodes that are already visited
