Challenge Problems
Push your limits with challenges.
Question 1
Given the following graph with 6 vertices represented as an adjacency list {1: [2, 3], 2: [1, 4], 3: [1], 4: [2, 5, 6], 5: [4], 6: [4]}, implement BFS starting from vertex 1. Provide the order of visited vertices and their levels.
💡 Hint: Track your progress with a queue and level records.
Question 2
Consider a graph where you need to compute the shortest path from vertex A to vertex D. Describe how you would implement BFS to find this path.
💡 Hint: Think about the relationships between vertices as you explore.
