Given a binary tree, find the maximum path sum. The path may start and end at any node in the tree. For example: Given the below binary tree, 1 / \ 2 3 Return6. ++++++++++++++++++++++++++++++++++++++++++ test.cpp: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 1...
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 not need to go through the root. For example: Given the below binary tree, \ 1. Return ...
分析:http:///2013/01/leetcode-binary-tree-maximum-path-sum.html For each node like following, there should be four ways existing for max path: 1. Node only (因为本题中的节点可能是负值!) 2. L-sub + Node 3. R-sub + Node 4. L-sub + Node + R-sub Keep trace the four path and...
public int maxPathSum(TreeNode root) { if (root == null) { return Integer.MIN_VALUE; } //左子树的最大值 int left = maxPathSum(root.left); //右子树的最大值 int right = maxPathSum(root.right); //再考虑包含根节点的最大值 int all = ...; return Math.max(Math.max(left, right...
1. Maximum Depth of Binary Tree 解法1: class Solution: def maxDepth(self, root: TreeNode) -> int: self.answer = 0 self.helper(root,0) return self.answer def helper(self,node,depth): if node is None: self.answer=max(self.answer,depth) else: self.helper(node.left,depth+1) self....
A Balanced Binary Tree is a type of binary search tree where the height of the tree is proportional to log base 2 of the number of elements it contains. This balanced structure ensures efficient searching, with elements being found by inspecting at most a few nodes. ...
