6 Questions
Which of the following is a key step in producing a topological ordering for a directed graph?
Finding a node with an indegree of zero and adding it to the ordering
What is the significance of a node with an indegree of zero in a topological ordering?
It is the first node in the ordering
What happens to a node once it is added to the topological ordering?
It and its outgoing edges are removed from the graph
How do we find the next node to add to the topological ordering after the first one?
Look for a node with an indegree of zero
What do we do if there are multiple nodes with an indegree of zero in the graph?
Choose any of them to add to the ordering
When do we stop adding nodes to the topological ordering?
When we're out of nodes
