Explanation: Maximum sum in a valid Binary search tree is obtained in a single root node with key equal to 2. Example 3: Input: root = [-4,-2,-5] Output: 0 Explanation: All values are negatives. Return an empty BST. Constraints: The number of nodes in the tree is in the range[...
Can you solve this real interview question? Maximum Sum BST in Binary Tree - Given a binary tree root, return the maximum sum of all keys of any sub-tree which is also a Binary Search Tree (BST). Assume a BST is defined as follows: * The left subtree
124. Binary Tree Maximum Path Sum 题目: Given a binary tree, find the maximum path sum. For this problem, a path is defined as any sequence of nodes from some starting node to any node in the tree along the parent-child connections. The path must contain at least one node and does n...

Given an integer array with no duplicates. A maximum tree building on this array is defined as follow: The root is the maximum number in the array. The left subtree is the maximum tree constructed from left part subarray divided by the maximum number. ...
So how can we find kth maximum given the binary search tree and the k as input? The idea isreverse inorder traversal. If we do the reverse inorder traversal then we will reach to the maximum node in the BST first. So, we need to keep a counter which will increment to find the kth...

Binary tree is a special kind of tree where each node has a maximum of two children. The topmost node in the tree is called 'root' node. The left reference of the root node is called the 'left child' while the right reference is called the 'right child' of the ro...
