Which traversal method is best suited for retrieving data 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 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 current node, and finally the right child.
Step 4: Apply in-order traversal to a BST. When you perform in-order traversal on a BST, you will visit the nodes in ascending order because of the properties of the tree.
Step 5: Conclude that in-order traversal is the best method for retrieving data in sorted order from a binary search tree.
