How does DFS traverse through a graph or tree?
- Explore nodes randomly
- Iteratively explore each branch until all nodes are visited
- Recursively explore each branch until all nodes are visited
- Traverse nodes level-wise
DFS traverses through a graph or tree by recursively exploring each branch until all nodes are visited. It starts at the root node, explores as far as possible, backtracks, and continues until all nodes are covered.
