Show hintHide hint
Think about what elements are needed to form a graph.
Question 2.
What does BFS stand for?
Show hintHide hint
Consider the order in which nodes are visited.
3Question 3.
What is the main purpose of BFS?

Question 5.
Given the following undirected graph, write pseudocode to perform BFS to find all connected components.
Show hintHide hint
Focus on marking nodes as you traverse.
