Finally, I tore the binary search tree by hand (the code can be run with detailed comments)

preface This paper contains the common methods of operating binary search tree, focusing on the deletion of binary search tree. Deletion is far more complex than insertion. There are many cases on the Internet that are not well considered. In a rage, I tore a Demo with detailed comments. Definition and properties of binary search tree Binary ...

2-3 Importance calculation for nodes in social network diagrams (25 points)

2-3 Importance calculation for nodes in social network diagrams (25 points) In social networks, individuals or units (nodes) are connected by certain relationships (edges). They are affected by these relationships, which can be interpreted as an interaction that spreads between interconnected nodes in the network and can be enhanced or weakene ...

Data structure -- c language implementation of recursive traversal of binary tree (super detailed notes / experimental report)

Data structure - c language implementation of recursive traversal of binary tree (super detailed notes / experimental report) Knowledge review Traversal of a binary tree means that each node in the binary tree is accessed only once according to a certain law. The access can calculate the data information of the node in the binary tree, and pr ...

Detailed explanation of common sorting algorithms

Bubble sorting Bubble sorting is basically the first sorting method we come into contact with in the learning process. The idea is also relatively simple, that is, after pairwise comparison, if the large number is in front of the small number, we will exchange the positions of the two, then go back and compare the two numbers. When you get ...

Data structure: understand binary search tree (JavaScript)

Introduction to binary search treeBinary search tree is a binary tree with a certain order of magnitude between node values. For each node in the tree:If its left subtree exists, the value of each node in its left subtree is not greater than the value of the node;If its right subtree exists, the value of each node in its right subtree is not le ...

Basis of data structure: Java version hand torn BST binary search tree (including pre order, middle order, post order, sequence traversal, and tree height calculation)

Prequel The graphical presentation in the article can be simulated at the following website: https://www.cs.usfca.edu/~galles/visualization/Algorithms.html 1, BST overview Like linked list, binary search tree is also a dynamic data structure. But its query efficiency is higher, and the average sharing time complexity of query is O(logn). F ...

Primary data structure: binary tree

Binary tree Linked lists and arrays are linear structures, and trees are nonlinear structures. Tree is a hierarchical structure defined by branching relationship. Social kinship and organization chart can be represented vividly by trees. 1 Definition and structure of tree 1.1 definition of tree Tree is ...

Data structure code Title ------- figure < Day01 >

Data structure code - Chart From the beginning of this blog, we have come to the code part of graph structure. For graph related code, we mainly focus on depth first and breadth first traversal algorithms. Let's first introduce the breadth first traversal algorithm. Introduction to breadth first algorithm 1. Diagram structure representati ...
