Challenge Problems
Push your limits with advanced challenges
Given a graph with vertices A, B, C, and D, and edges with weights between them, find the shortest path from A to D using Dijkstra's algorithm.
💡 Hint: Don't forget to update the neighbors' costs after visiting a vertex.
Explain why Dijkstra's algorithm fails with negatively weighted edges, and provide an example.
💡 Hint: Consider paths that could 'get shorter' after visiting them.
