Which of the following is true about a binary search tree (BST)?
Step 1: Understand what a binary search tree (BST) is. A BST is a type of data structure that stores values in a way that for any given node, all values in the left subtree are smaller, and all values in the right subtree are larger.
Step 2: Learn about inorder traversal. Inorder traversal is a method of visiting nodes in a tree where you first visit the left child, then the current node, and finally the right child.
Step 3: Apply inorder traversal to a BST. When you perform an inorder traversal on a BST, you will visit the nodes in a specific order that respects the BST property.
Step 4: Recognize the result of the inorder traversal. Because of the way a BST is structured, the values you visit during an inorder traversal will be in non-decreasing order, meaning they will be sorted from smallest to largest.
