Which traversal method can be used to obtain a sorted order of elements in 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 than the parent node.
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 parent node, and finally the right child.
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 use if you want to obtain a sorted order of elements in a binary search tree.
