Questions & Step-by-Step Solutions
In which traversal method are nodes visited in ascending order for 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 pre-order, in-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. Because of the properties of a BST, visiting nodes in in-order will result in visiting them in ascending order.
Step 5: Conclude that in-order traversal is the method that visits nodes in ascending order for a binary search tree.
