LeetCode - Validate Binary Search Tree - Alkesh blogs
WebDec 2, 2024 · Example 1: LeetCode Input: root = [3, 9, 20, null, null, 15, 7] Output: [ [3], [20, 9], [15, 7]] Example 2: Input: root = [1] Output: [ [1]] Example 3: Input: root = [] Output: []... WebInput: root = [5,3,1] Output: false Explanation: The values of the root, its left child, and its right child are 5, 3, and 1, respectively. 5 is not equal to 3 + 1, so we return false. Constraints: The tree consists only of the root, its left child, and its right child.-100 <= Node.val <= 100 rta bus route
LeetCode #652 Find Duplicate Subtrees by Len Chen Medium
WebWhere each function call will represent a subtree which has root node called as ‘root’. We traverse the tree by a recursive function starting from the root node. So the base case is when the subtree is empty i.e. root is NULL. So we return depth as 0. if root is not NULL, call the same function recursively for its left child and right child. WebA rooted treeis a tree that has a single root node, and all edges are oriented to be outgoing from the root. An ancestorof a node is any node on the path from the root to that node … WebPath Sum II LeetCode Solution – Given the root of a binary tree and an integer targetSum, return all root-to-leaf paths where the sum of the node values in the path equals targetSum. Each path should be returned as a list of the node values, not node references. A root-to-leaf path is a path starting from the root and ending at any leaf node. rta bus service in liwan
