binary socks

In my impression, it is a common problem to convert into one another, so in Python, the following code should be accepted as util. This is a search from the Internet also can also be a Python binary conversion, verified can be used.

Binary tree is a nonlinear structure, and traversal of binary tree is accomplished by recursive or non-recursive traversal by means of a stack assist. When a binary tree is used as a storage structure, it takes a node to get the left child and the right child of the node, and can not directly get the precursor or successor of any of the nodes ' traversal sequence

Given a binary tree, return the inorder traversal of its nodes ' values.For Example:given binary Tree [1,null,2,3] , 1 2 / 3Return [1,3,2] .Note: Recursive (Recursive) solution is trivial, could do it iteratively (iteration)?Ideas:Solution One: The recursive method is very simple,(1) If root is empty, NULL is returned;(2) If Root->left = NULL, returns the middle-order traversal element of the

Determine if the binary tree is a complete binary tree. The definition of a complete binary tree is that the former n-1 layer is full, the nth layer if there is a vacancy, is missing on the right side, that is, the nth layer of the rightmost node, its left is full, the right is empty.The description of this problem has been prompted to understand the method, usin

Topic:Given a binary tree, return all root-to-leaf paths.For example, given the following binary tree: 1/ 2 3 5All root-to-leaf paths is:["1->2->5", "1->3"]Ideas:Pre-order recursion can be.Code Listing 1:/** * Definition for a binary tree node. * struct TreeNode {* int val; * TreeNode *left; * TreeNode *right; * TreeNode (int x): Val (x), left (NULL) ,

leetcode105The binary tree can be reconstructed by the first order and the middle order of the binary tree, or by the first order and the sequential traversal. The value of the root node of the two-fork tree can be found by the ordinal traversal, then the node is divided into the Saozi right subtree by the middle order/post traversal.In general, there are two methods of iteration and recursion to reconstruc

Java generates and traverses binary trees, and java generates Binary Trees. In java, binary tree and linked list are implemented by defining object references of this class in the class. For example class Tree{ int data; Tree left; Tree right;} In this way, when we create a new Tree object, the object will have two objects, left and right, so that the co

Binary Search, binary search Binary Search, as its name implies, is a component search. When binary lookup is used, data must be sorted, which is the prerequisite for Binary lookup. The basic implementation of this algorithm is as follows: 1. Sort data first 2. Determine the
