Which traversal method is commonly used to retrieve elements in sorted order from a binary search tree?
Step 1: Understand what a binary search tree (BST) is. A BST is a type of data structure where each node has a value, and the left child has a smaller value while the right child has a larger value.
Step 2: Learn about tree traversal methods. These 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 this method, you visit the left child first, then the node itself, 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 increasing order of their values.
Step 5: Conclude that in-order traversal is the method used to retrieve elements in sorted order from a binary search tree.
