What is backtracking in the context of DFS?
- Reverting to the previous step and trying a different option
- Moving backward in the graph to explore other branches
- Ignoring previously visited nodes and going forward
- Reducing the depth of the recursion stack
Backtracking in DFS involves reverting to the previous step and trying a different option when exploring a solution space. It is particularly useful in problems with multiple decision points and unknown paths.
