Questions & Step-by-Step Solutions

Which of the following is NOT an application of DFS?
  • Step 1: Understand what DFS (Depth-First Search) is. It is a method for exploring nodes and edges in a graph.
  • Step 2: Know that DFS explores as far as possible along each branch before backtracking.
  • Step 3: Recognize that DFS is used for applications like finding connected components, topological sorting, and solving puzzles.
  • Step 4: Identify that finding the shortest path means looking for the least number of edges or the least weight in a graph.
  • Step 5: Realize that DFS does not guarantee the shortest path because it may explore longer paths before finding a shorter one.
  • Step 6: Conclude that finding the shortest path is NOT an application of DFS.
