Questions & Step-by-Step Solutions
Which traversal method visits all nodes of a binary tree in order?
Step 1: Understand what a binary tree is. A binary tree is a structure where each node has at most two children, referred to as the left child and the right child.
Step 2: Learn about tree traversal methods. Traversal methods are ways to visit all the nodes in a tree.
Step 3: Identify the different types of traversal methods. The main types are in-order, pre-order, and post-order.
Step 4: Focus on in-order traversal. In in-order traversal, you visit the left subtree first, then the current node, and finally the right subtree.
Step 5: Realize that in-order traversal visits nodes in sorted order for a binary search tree, meaning it will list the values from smallest to largest.
