Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You have a graph with 10 vertices and the edges {(1,2), (2,3), (3,4), (4,5), (1,6), (6,7), (6,8), (5,9)}. Describe the BFS traversal starting from vertex 1.

💡 Hint: Keep track of the levels while traversing!

Challenge 2 Hard

Given an example of both an adjacency matrix and list for the edges mentioned above, calculate the time complexity of BFS for both representations.

💡 Hint: Make sure to consider the number of edges and how they relate.
