WebMar 24, 2024 · There are two ways we can trace the path in the iterative DFS. In one approach, after visiting a node, we memorize which node its parent is in the search tree. That way, after finding the target node, we can reconstruct the path by following the parent-child hierarchy. In the other method, we store the full path to each node.
