Challenge Problems
Push your limits with advanced challenges
Given a directed graph with weights, apply the Floyd-Warshall algorithm to find all pairs shortest paths. Write down each step leading to the final matrix.
💡 Hint: Keep track of how weights update as you consider intermediate vertices.
Construct an example with a negative cycle and demonstrate what happens when using Floyd-Warshall.
💡 Hint: Think about what happens if a path gets shorter with each iteration through the cycle.
