1373. Maximum Sum BST in Binary Tree

LeetCodeDynamic ProgrammingTreeDepth-First SearchBinary Search TreeBinary TreeOpen on judge ↗

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 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. - Both the left and right subtrees must also be binary search trees
