Challenge Problems
Push your limits with advanced challenges
Given a directed graph, implement the BFS algorithm and provide the pseudocode, explaining why each step is necessary in the context of pathfinding.
💡 Hint: Think about the main objectives of each BFS strategy.
Describe how you would adjust the BFS algorithm to handle weighted graphs where the shortest path is defined not just by the number of edges but by edge weight. Suggest an algorithm for this.
💡 Hint: Consider how BFS could misidentify paths if weights are involved.
