Questions & Step-by-Step Solutions

Which of the following problems can be solved using DFS?
  • Step 1: Understand what DFS (Depth-First Search) is. It is a method for exploring nodes and edges in a graph or tree structure.
  • Step 2: Identify problems that can be solved using DFS. Examples include finding paths in a maze and performing topological sorting.
  • Step 3: Recognize that DFS is not suitable for finding the shortest path in a weighted graph because it does not consider the weights of the edges.
  • Step 4: Conclude that while DFS is useful for certain problems, it has limitations in others, particularly when optimal solutions are required.
