WebStep 2/3. Step 3/3. Final answer. Transcribed image text: Write the function isBST (t) that receives a binary tree t and determines if t is a binary search tree. For example, your function should return True if it receives the tree on the left and False if it receives the tree on the right (since key 68 is on the left subtree of key 66). WebMar 7, 2024 · Idea For each subtree, we return 4 elements. the status of this subtree, 1 means it's empty, 2 means it's a BST, 0 means it's not a BST size of this subtree (we only care about size of BST though) the minimal value in this subtree

Validate Binary Search Tree - Given the root of a binary tree, determine if it is a valid binary search tree (BST). A valid BST is defined as follows: * The left subtree of a node contains only nodes with keys less than the node's key. * The right subtree of a node contains only nodes with keys greater than the node's key. * …

WebApproach. First, we do inorder traversal of the given tree and store it in an array. Then we check if the array is sorted in increasing order. Then we say it is a binary search tree else it is not a binary search tree.
