Challenge Problems
Push your limits with advanced challenges
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.
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.
