Binary tree path sum
WebGiven a binary tree and a sum, determine if the tree has a root-to-leaf path such that adding up all the values along the path equals the given sum. For example: Given the below binary tree and sum = 22, 5 / \ 4 8 / / \ 11 13 4 / \ \ 7 2 1 return true, as there exist a root-to-leaf path 5->4->11->2 which sum is 22.

WebFeb 7, 2024 · Note that the path does not need to pass through the root. The path sum of a path is the sum of the node's values in the path. Given the root of a binary tree, return the maximum path sum of any path. Example 1: Input: root = [1,2,3] Output: 6 Explanation: The optimal path is 2 -> 1 -> 3 with a path sum of 2 + 1 + 3 = 6. Example 2: WebGiven a binary tree, write an efficient algorithm to find the maximum path sum between any two nodes in it. The path can start and end at any node in the tree and need not go through the root. For example, the maximum sum path in the following binary tree is highlighted in green: Practice this problem.
