Question: Which of the following is a characteristic of Depth-First Search (DFS)?

Options:

Correct Answer: Can be implemented using recursion

Solution:

DFS can be implemented using recursion, which allows it to explore as far as possible along each branch before backtracking.

Which of the following is a characteristic of Depth-First Search (DFS)?

Which of the following is a characteristic of Depth-First Search (DFS)?

Step 1: Understand that Depth-First Search (DFS) is a method for exploring nodes in a graph or tree.
Step 2: Recognize that DFS starts at a root node and explores as far down one branch as possible.
Step 3: Learn that if it reaches a node with no unvisited neighbors, it backtracks to the previous node.
Step 4: Note that DFS can be implemented using recursion, which means it can call itself to go deeper into the graph.
Step 5: Realize that this recursive approach allows DFS to explore all nodes along a path before returning to explore other paths.
