Check if binary tree is sum tree or not gfg
WebTo determine whether a given binary tree is a BST, keep track of the last visited node while traversing the tree. Then for each encountered node in the inorder traversal, check whether the last visited node is smaller (or smaller/equal, if duplicates are to be allowed in the tree) compared to the current node. WebGiven the rootof a binary search tree and an integer k, return trueif there exist two elements in the BST such that their sum is equal tok, orfalseotherwise. Example 1: Input:root = [5,3,6,2,4,null,7], k = 9 Output:true Example 2: Input:root = [5,3,6,2,4,null,7], k = 28 Output:false Constraints:
