Which traversal method is commonly used to print the nodes of a binary search tree in sorted order?
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 means visiting each node in the tree in a specific order.
Step 3: Identify the three common 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: Realize that when you perform in-order traversal on a binary search tree, you visit the nodes in ascending order, which means you get the sorted order of the values.
