Which traversal method visits the root node last?

Which traversal method visits the root node last?

Step 1: Understand what a tree is. A tree is a data structure with nodes, where each node can have a left and right child.
Step 2: Learn about tree traversal methods. These are ways to visit all the nodes in a tree.
Step 3: Identify the three main traversal methods: Pre-order, In-order, and Post-order.
Step 4: In Pre-order traversal, you visit the root node first, then the left subtree, and finally the right subtree.
Step 5: In In-order traversal, you visit the left subtree first, then the root node, and finally the right subtree.
Step 6: In Post-order traversal, you visit the left subtree first, then the right subtree, and finally the root node.
Step 7: Conclude that Post-order traversal is the method that visits the root node last.
