Questions & Step-by-Step Solutions
Which of the following statements about DFS is true?
Step 1: Understand what DFS stands for. DFS means Depth-First Search, which is a way to explore or search through data structures like trees or graphs.
Step 2: Learn about how DFS works. It starts at a root node and explores as far as possible along each branch before backtracking.
Step 3: Recognize that DFS can be done in two main ways: using a stack or using recursion.
Step 4: Know that recursion is a method where a function calls itself to solve smaller parts of the problem.
Step 5: Realize that using recursion is a common and simple way to implement DFS because it naturally follows the depth-first approach.
