What is the difference between DFS and BFS (Breadth-First Search)?
- BFS explores neighbor nodes before moving deeper
- BFS is less memory-efficient than DFS
- DFS always finds the shortest path in a graph
- DFS explores as far as possible before backtracking
The main difference is in the order of exploration. DFS explores as far as possible along each branch before backtracking, while BFS explores all neighbor nodes before moving deeper, resulting in a level-by-level approach.
