Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a tree structure, implement BFS to determine if a specific target value exists. Keep track of parent nodes for path reconstruction.

💡 Hint: Make sure to update your parent array while exploring.

Challenge 2 Hard

Explore a dense graph using BFS. Compare the time taken with an adjacency matrix vs. an adjacency list. Report findings.

💡 Hint: Count how many edges and vertices exist to justify your observations.
