Questions & Step-by-Step Solutions

Which traversal method uses a stack to explore nodes?
  • Step 1: Understand what a traversal method is. It is a way to visit all the nodes in a tree or graph.
  • Step 2: Learn about Depth-First Search (DFS). It is one of the methods used for traversing trees or graphs.
  • Step 3: Know that DFS explores as far as possible down one branch before moving to another branch.
  • Step 4: Recognize that DFS uses a stack data structure to keep track of the nodes it needs to visit next.
  • Step 5: Conclude that since DFS uses a stack to explore nodes, it is the correct answer to the question.
