Article directory Realization of Non-recursive Algorithm for Preorder, Inorder and Postorder Traversal of Binary Linked List preorder traversal Inorder traversal post order traversal Implementation of non-recursive algorithm for preorder, inorder and postorder traversal of binary linked list The good things are written in the front: I have been unable to remember the output results of […]
Data structure — tree (with C++ code implementation, preorder, postorder, inorder traversal, tree depth, including recursive and non-recursive traversal with complete C++ code)
1. What is a tree? What are the more famous applications of trees? A tree is a data structure that consists of several nodes (nodes) connected to each other by edges (edges). Trees have the following characteristics: 1. Each node has only one parent node, except the root node. 2. Each node can have multiple […]
Implementation of Inorder Thread Binary Tree: Code and Analysis and Running Results
Analysis: /* * Use the inorder thread binary tree to find the inorder predecessor and inorder successor of the binary tree node * (1) Create a threaded binary tree * (2) Perform inorder threadization on this thread binary tree ====>> become an inorder thread binary tree * (3) Use the clues of the inorder thread […]
Create a binary tree from preorder and inorder
Algorithm Analysis First of all, the preorder is accessed in the order of root -> left subtree -> right subtree, that is to say, the order given by the preorder must first give the root node , then we can recursively determine the root node of each subtree in turn according to the order of […]

106 Construct a binary tree from inorder and postorder traversal sequences
106 Construct a binary tree from inorder and postorder traversal sequences Given two integer arrays inorder and postorder, where inorder is the inorder traversal of a binary tree and postorder is the postorder traversal of the same tree, please construct and return this binary tree. Example 1: Input: inorder = [9,3,15,20,7], postorder = [9,15,7,20,3] Output: […]
Create threaded binary tree – traversal of inorder threaded binary tree (C++ implementation)
Create the illustrated binary tree and thread it The preorder traversal sequence is: ABDGECF The chain structure of the thread binary tree is described as follows: typedef struct ThreadNode{ char data; struct ThreadNode *lchild; struct ThreadNode *rchild; int ltag, rtag;//left and right clue flags }ThreadNode,*ThreadTree; Build a binary tree with preorder traversal: void creat_ThreadTree(ThreadTree & […]
