Explain the difference between BFS and DFS (Depth-First Search) in terms of traversal strategy.
- BFS always finds the shortest path
- BFS explores nodes level by level, while DFS explores as far as possible along each branch before backtracking
- DFS guarantees a topological order of nodes
- DFS uses a queue for traversal
The main difference lies in traversal strategy: BFS explores level by level, while DFS explores as far as possible along each branch before backtracking. BFS ensures the shortest path, while DFS may not. DFS uses a stack for traversal.
