How does BFS handle graphs with cycles? Does it avoid infinite loops?
- BFS automatically breaks out of cycles due to its nature of exploring nodes in a breadth-first manner.
- BFS can enter an infinite loop in the presence of cycles unless proper mechanisms are in place to mark and track visited nodes.
- BFS cannot handle graphs with cycles and always results in an infinite loop.
- BFS inherently avoids infinite loops in graphs with cycles by maintaining a visited set of nodes.
BFS avoids infinite loops in graphs with cycles by maintaining a visited set. This set ensures that already visited nodes are not processed again, preventing the algorithm from getting stuck in an infinite loop. Proper implementation is essential to handle cyclic graphs effectively.
