WebStand out from the crowd. Prepare with Complete Interview Preparation. Given a Binary Tree, check if all leaves are at same level or not. Example 1: Input: 1 / \ 2 3 Output: 1 Explanation: Leaves 2 and 3 are at same level. Example 2: Input: 10 / \ 20 30 / \ 10 15 Output: 0 Explanation: Leaves 10, 15 and 30 are not at same level. Your Task: WebIf the node is greater than the children’s sum, fix the node by either updating the left or the right subtree with the difference between the root and its children and then recursively fix the subtree. If the node is the same as the children’s sum, then do nothing. Here’s a dry run of the algorithm on the above example. 1. Fix the left ... 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.
