Which traversal method is best for obtaining a sorted list from a binary search tree?
Step 1: Understand what a binary search tree (BST) is. A BST is a tree data structure where each node has at most two children, and the left child is less than the parent node, while the right child is greater.
Step 2: Learn about tree traversal methods. Common methods include in-order, pre-order, and post-order traversals.
Step 3: Focus on in-order traversal. In this method, you visit the left child, then the parent node, and finally the right child.
Step 4: Apply in-order traversal to a binary search tree. When you do this, you will visit the nodes in ascending order.
Step 5: Conclude that in-order traversal is the best method for obtaining a sorted list from a binary search tree.
