Question:Invert a binary tree. 4 / 2 7/\ /1 3 6 9To 4 / 7 2/\ /9 6 3 1Trivia:This problem is inspired by this original tweets by Max Howell: google:90% of our engineers with the software you wrote (Homebrew), but can ' t invert a binary tree on a Whitebo ard so fuck off. Analysis:Problem Description: Give a binary tree, then replace it with the left and right sub-tree.Idea: This topic should be reflected to recursion first. There are two condi

one of the one of the the and the It's parent. The parent would then test it left and right subtree if each contain one of the nodes. If Yes, then the parent must is the LCA and we pass their parent up to the root. If not, we pass the lower node which contains either one of the one of the same nodes (if the left or right subtree contains either p or q), or NULL (if both the left and right subtree does not contain either P or Q) up.2. Use of stacks, find, nodes separately and compare their trace

The following code needs to be added to the 1.benas XML fileclass= "Org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor"/>The 2.beans node has a property that needs to be set default-autowire= "Bytype", that is, whether the automatic rig is based on the configured bean type lookup or otherwise, such as the Bean's nameWith the above settings, the @autowired annotations on the properties (fields) of the class can be used to

Given a binary tree, return the inorder traversal of its nodes ' values.For example:Given binary Tree {1,#,2,3} , 1 2 / 3Return [1,3,2] .Note:recursive solution is trivial, could do it iteratively? Problem Solving Ideas: In-order (symmetric) Traverse the left subtree by recursively calling the In-order function Display the data part of the root element (or current element) Traverse the right subtree by recursively calling the In-order function Inorder t

Given a binary tree containing digits from only 0-9 , each root-to-leaf path could represent a number.An example is the Root-to-leaf path 1->2->3 which represents the number 123 .Find The total sum of all root-to-leaf numbers.For example, 1 / 2 3The Root-to-leaf path 1->2 represents the number 12 .The Root-to-leaf path 1->3 represents the number 13 .Return the sum = + = 25 ./*** Definition for a binary tree node. * public class TreeNode {* int val; * TreeNode left; * TreeNode

state "top left and right" is the original initial state of "lower left upper right". then rotate 90 degrees, it becomes the initial state of the "lower left top", and so on. That is, we can set a state transfer array to represent this situation. Using tp[i][j] means that when the state is I (I at this time the range is 0~3), its first J subscript corresponding to the initial gear array should be what the subscript (subscript starting from 1, note and the status of the range of values separated
