## 13_JavaScript data structure and algorithm binary search tree

JavaScript data structure and algorithm (XIII) binary search tree
Binary search tree
Binary Search Tree (BST), also known as binary sort tree and Binary Search Tree.
Binary search tree is a binary tree and can be empty.
If it is not empty, the following properties are met:
Condition 1: all key values of non empty left subtree are less than ...

## Expression evaluation based on binary tree (C + +, detailed idea)

describe
Enter an expression (the numbers in the expression are positive integers less than 10), use a binary tree to represent the expression, create an expression tree, and then use the traversal operation of the binary tree to find the value of the expression.
input
Multiple sets of data. Each row ...

## Common algorithms of binary tree

1. Traversal of binary tree
1.1 preorder traversal Middle - > left - > right
public static void preOrderRecur(Node head){
if(head == null){
return;
}
//Printing at the beginning is the first order traversal, printing at the middle position is the middle order traversal, and printing at the end is the second order traversal.
System ...

## [AVL balanced binary tree] JAVA code implementation

Realization idea
AVL balanced binary tree adds the balancing function on the basis of binary search tree, that is, after inserting data according to the rules of balanced binary tree, it is still necessary to ensure that the depth difference between the left and right subtrees of any node does not exceed 1, so as to ensure the query effici ...

## [HBU-DS] 7-5 tribes (and search Collection)

7-5 tribes (20 points)
subject
In a community, everyone has his own small circle and may belong to many different circles of friends at the same time. We think that all friends of friends are in one tribe, so please count how many disjoint tribes there are in a given community? And check whether any two people belong to the same tribe.
Input ...

## Application of Binary Tree Traversal (Build Binary Tree, Find Tree Depth, Copy Binary Tree)

Establishing Binary Tree Storage Structure--Binary Chain List
The same binary tree can be built in different order, which corresponds to different codes and different user inputs. The process of building a binary tree in different order is different but the final result is the same, so the binary tree can be built by traversing in order, but t ...

## Data structure - binary tree

1. Why do you need a tree data structure?
Analysis of array storage mode
Advantages: it is fast to access elements by subscript. For ordered arrays, binary search can also be used to improve the retrieval speed.Disadvantages: if a specific value is to be retrieved, or the inserted value (in a certain order) will move as a whole, the eff ...
