‘Go back’ generally can be realized using data structure ——stack—— or by recursion. And if we use stack, it means we would need to push each node we visited in the process of exploring each branch, and pop when we can’t explore further starting from current node. BFS In tree ...

a logical tree. The Wiki example uses a chessboard and a specific problem - you can look at a specific move, and eliminate it,then backtrack to the next possible move, eliminate it, etc.How to Implement DFS and BFS DFS In tree structure, DFS means we always start from a root node ...
The implementation of BFS requries the use of the queue data structure while the implementation of DFS can be done in a recursive manner. For more details on BFS and DFS, you may refer toIntroduction to Algorithmsor these two nice videos:BFS videoandDFS video. ...
