Challenge Problems
Push your limits with challenges.
Question 1
Given a graph with vertices A, B, C, and D with weights: A to B (1), A to C (4), B to C (2), B to D (6), and C to D (1). Using Dijkstra's algorithm from A, calculate the shortest path to D.
💡 Hint: Trace the paths starting from A and calculate the weights.
Question 2
Explain the shortcomings of Dijkstra's algorithm when applied to a graph with negative edges and provide an example of why it fails.
💡 Hint: Consider paths and how weights impact total distance, especially when negative options are available.
