Question 1.
Define a graph.
Show hintHide hint
Think about nodes and their connections.
Question 2.
What is the difference between undirected and directed graphs?
Show hintHide hint
Consider the flow of connections.
3Question 3.
What does a directed edge in a graph represent?
- Two-way connection
- One-way connection
- No connection
Show hintHide hint
Remember the flow of direction!
4Question 4.
An adjacency matrix is symmetric for which type of graph?
- True
- False
Show hintHide hint
Think about undirected edges!
Question 5.
Given a weighted graph, explain how you'd modify the adjacency matrix to represent weights instead of binary connections.
Show hintHide hint
Consider what information the weights convey.
Question 6.
Design an algorithm using BFS to find the shortest path in an unweighted graph, then explain key steps.
Show hintHide hint
Think about how you would ensure all connections are checked systematically.
