Which of the following traversal methods can be used to obtain a sorted order of 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 for any given node, all values in the left subtree are less than the node's value, and all values in the right subtree are greater.
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 subtree first, then the root node, and finally the right subtree.
Step 4: Apply in-order traversal to a binary search tree. When you perform in-order traversal on a BST, you will visit the nodes in ascending order because of the properties of the BST.
Step 5: Conclude that in-order traversal is the method to obtain a sorted order of a binary search tree.
