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.
