Challenge Problems
Push your limits with advanced challenges
Given the following graph composed of vertices and edges, write a BFS algorithm that starts with vertex 1 and outputs the order of vertices visited.
💡 Hint: Consider how neighbors are added to the queue.
Design a graph with 10 vertices and at least 8 edges such that BFS starting from vertex 1 visits vertices in the order of 1, 2, 3, 4, 5, .... Write what this order reveals about the graph's structure.
💡 Hint: Visualize how each vertex connects and ensures every next vertex is reached during exploration.
