Depth-first search (DFS) is a fundamental search algorithm that is used to traverse graphs or trees. It explores a path as deep as possible and backtracks when it hits a dead end.
In this post, we review the DFS and implement it in both recursive and iterative versions. We test both versions with a given graph. Moreover, we bring the Python code to find a path between two nodes.
The complete Python code is available at the mentioned GitHub page, which also includes the code to find all paths between two nodes
.
