Which traversal method of a binary tree is commonly used to generate a sorted list of values?
Step 1: Understand what a binary tree is. A binary tree is a data 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. Common methods include in-order, pre-order, and post-order.
Step 3: Focus on in-order traversal. In in-order traversal, you visit the left child first, then the current node, and finally the right child.
Step 4: Realize how in-order traversal works. When you perform in-order traversal on a binary search tree (BST), it visits the nodes in ascending order.
Step 5: Conclude that in-order traversal is used to generate a sorted list of values because it processes the nodes in the correct order.
