Topic:Given A binary search tree (BST), find the lowest common ancestor (LCA) of the Given nodes in the BST.According to the definition of the LCA in Wikipedia: "The lowest common ancestor is defined between," nodes V and W as the L Owest node in T, have both V and W as descendants (where we allow a node to be a descendant of itself).

Given a binary tree, find its maximum depth.The maximum depth is the number of nodes along, the longest path from the root node to the farthest leaf node.Finding the maximum depth of a binary tree/*** Definition for a binary tree node. * public class TreeNode {* int val; * TreeNode left; * TreeNode rig Ht * TreeNode (int x) {val = x;} }*/ Public classSolution { Public intmaxDepth (TreeNode root) {if(Root = =NULL) { return0; }

First define the storage structure of the binary tree:　　1 struct TreeNode {2 int Val; 3 TreeNode * Left; 4 TreeNode * Right; 5 6 TreeNode (int V, treenode* l = null, TreeNode *r = null)7 : Val (v), left (l), rig HT (r) {}8 };1. Recursive method ("Beauty of Programming" 3.10)The binary tree itself has recursive attribution, and usually we can solve it by recursive method. If you want to access the K-tier node, you can actually go

part of the test you want to be tested as a data-driven test. Then you can create a data source for this part of the test, such as the access database containing data. Data can be bound to multiple locations in the web test. You can add data bindings from two locations: A. add data binding for a query string parameter or form publishing form B. Add the following content directly in a shortcut: 3. Access MethodWhen bound to a data source, Team edition for testers supports sequential access

Topic:Given a binary tree struct Treelinknode { treelinknode *left; Treelinknode *right; Treelinknode *next; }Populate each of the next pointer to the next right node. If There is no next right node, the next pointer should are set to NULL .Initially, all next pointers is set to NULL .Note: Constant extra space. You could assume that it was a perfect binary tree (ie, all leaves was at the same level, and every parent had both children). For example. Given t

First, Description:Second, the idea:Binary sort tree (BST), the result of the middle sequence traversal must be a non-descending sequence (from Baidu Encyclopedia);In this case, the definition of BST is either greater than or small with, that is, the traversal result can only be an increment sequence, it can be judged whether the sequence of sequential traversal of the result series is an incremental sequence to determine if it is a legitimate BST;Another approach is to use recursion;Third, the

Given a binary tree and a sum, determine if the tree has a root-to-leaf path such this adding up all the values along the Path equals the given sum.For example:Given the below binary tree sum = 22 and, 5 / 4 8 / / / 4 / \ 7 2 1Return true, as there exist a root-to-leaf path 5->4->11->2 which sum is 22.Given a tree and a number, judge whether the number is from the root node to the leaf node.Recursive impl
