## Data structure - sequential storage of binary tree

Concept and structure of binary tree concept A binary tree is a finite set of nodes. The set is either empty, or a root node plus two trees, also known as left subtree and right subtree Binary tree. Characteristics of binary tree: Each node has at most two subtrees, that is, the binary tree does not have nodes with a degree greater than 2 ...

## Linear table and its sequential storage

Linear table Definition and characteristics of linear table 1. A finite sequence composed of n (n > = 0) elements with the same data type is called a linear table. N is the table length. When n=0, it is called an empty table. 2 characteristics of non empty linear structure: ① There is and only one start node, which has no direct precursor. ...

## Simulation Implementation of HashMap

To facilitate implementation and highlight key points, specify key as String type and Value as Integer class. In practice, if the key type is its own implementation class, the hashCode() and equals() methods of the class must be rewritten. The hashCode() method is rewritten because the hashCode() method needs to be called when finding the subsc ...

## Recursive functions and examples

definition: A calculation process in which the results of the previous step or steps are used in each step is called recursive. Functions defined by recursive processes are called recursive functions, such as continuous addition, continuous multiplication and factorial. All recursive functions are computable, that is, they can work. Classical r ...

## This may be the most detailed HashMap!

Hand tear HashMap source code The article has been synchronized to the GitHub open source project: Java supernatural Road HashMap has always been the focus of the interview. Today, let's learn about its source code! First, let's take a look at the inheritance structure of Map Source code analysis What is hash **Hash, gene ...

## Assembly language: experiment 10: writing subroutines

Experiment 10 programming subroutine This experiment needs to write three subprograms to understand several common problems and master the methods to solve these problems. 1. Display string problem Subroutine description Tips Solution Similar to the style of previous articles, they all use the description in Mr. Wang Shuang's origi ...

## java implementation of a simple binary tree, hold a big move

2. Complete binary tree Definition: in a binary tree, only the degree of the lowest two nodes can be less than 2, and the leaf nodes of the lowest layer are concentrated in several positions on the left. Such a binary tree is called a complete binary tree. Features: leaf nodes can only appear in the lowest layer and sub lower layer, and the l ...

## Data structure and algorithm HASH table

hash table definition Let's talk about the definition of hash table first: hash table is a data mapping structure that looks for values according to key codes. This structure looks for the place where values are stored by mapping the key codes. ...

## Basic summary of data structure and algorithm ------ 4. Linked list structure

Linked list is a data structure that is easy to understand and difficult to apply among all data structures. This time, it only provides a basis for introducing stacks and queues. The linked list is mainly explained in the advanced class. 1, Linked list In fa ...
