Which traversal method can be implemented using recursion?

Step 1: Understand what traversal methods are. They are ways to visit all the nodes in a tree or graph.
Step 2: Learn about Depth-First Search (DFS). It goes deep into a branch before backtracking.
Step 3: Recognize that DFS can be implemented using recursion. This means you can call the same function within itself to explore nodes.
Step 4: Understand Breadth-First Search (BFS). It explores all neighbors at the present depth before moving on to nodes at the next depth level.
Step 5: Note that BFS typically uses a queue and is usually implemented iteratively, not recursively.
