Questions & Step-by-Step Solutions
Which traversal method is used to retrieve nodes in sorted order from a binary search tree?
Step 1: Understand what a binary search tree (BST) is. A BST is a type of 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. Traversal methods are ways to visit all the nodes in a tree.
Step 3: Identify the different types of traversal methods: in-order, pre-order, and post-order.
Step 4: Focus on in-order traversal. In this method, you visit the left child first, then the parent node, and finally the right child.
Step 5: Apply in-order traversal to a binary search tree. When you do this, you will visit the nodes in ascending order because of the properties of the BST.
Step 6: Conclude that in-order traversal is the method used to retrieve nodes in sorted order from a binary search tree.
