💡 Hint: Think about the meaning of breadth in exploring a graph.

Question 2

True or False: BFS can only be used on unweighted graphs.

  • True
  • False

💡 Hint: Consider if BFS ensures the shortest path in all scenarios.

Challenge Problems

Push your limits with challenges.

Question 1

Given a graph representation of a social network, construct a BFS traversal starting from a specified user and list all the connections made. Then reconstruct the path back to the originating user for a selected connection.

💡 Hint: Ensure you note how many levels deep each connection goes and use parents to trace the full path.

Question 2

Create a graph representing a course prerequisite structure and demonstrate how BFS can be used to find if a specific course can be reached given a set of enrolled courses. Then indicate the path taken from any enrolled course to that target course.

💡 Hint: Think of enrolled courses as multiple starting points and track the paths with parent pointers.
