MindMap Gallery Chapter 3 - Algorithm Basics
Algorithm Basics 1: What is an algorithm and Big O notation? An algorithm is a set of instructions to complete a task. Any piece of code can be considered an algorithm. An algorithm is a solution to a problem through a finite process. Big O notation: Big O notation is a special...
Edited at 2022-11-21 21:52:30Ce calendrier annuel, créé avec EdrawMax, présente une disposition claire et organisée des mois de janvier à décembre. Chaque mois est affiché dans un cadre distinct, montrant les jours de la semaine et les dates correspondantes. Les weekends (samedis et dimanches) sont mis en évidence pour une meilleure visibilité. Ce format est idéal pour la planification et l'organisation des activités tout au long de l'année, offrant une vue d'ensemble rapide et facile à consulter.
This quarterly calendar overview for 2026, created with EdrawMax, presents a structured and colorful layout of the entire year divided into four quarters. Each quarter is displayed in a separate column, showcasing the months within that quarter in a clear grid format. The days of the week are labeled, and each date is marked within its respective cell, allowing for easy identification of dates across the year. This calendar is an excellent tool for long-term planning, providing a comprehensive view of the year at a glance.
This weekly calendar for 2026 is designed using EdrawMax to provide a detailed and organized view of each week, starting from January. The left side features a mini monthly calendar for quick reference, highlighting the current week in yellow. Below it, there's a section for weekly goals to help prioritize tasks. The main area is a time-grid from 6:00 AM to 12:00 AM, divided into half-hour slots, allowing for precise scheduling of daily activities throughout the week. This layout is ideal for managing a busy schedule efficiently.

Experience the computer problem-solving process
manual problem solving process
computer problem solving process
①Analyze the problem
②Design algorithm
③Write a program
④Debug and run the program
Algorithm and description
algorithm
Concept: A method of using computers to solve a problem
feature
①Finiteness
②Certainty
③Data input
④Data output
⑤Feasibility
Description of algorithm
Common ways to describe algorithms
①Natural language description algorithm
Concept: It is the language that people use daily, such as Chinese, English, etc. to describe algorithms
②Flowchart description algorithm
Concept: It is a representation method that uses a program block diagram to describe an algorithm.
③Pseudocode describing algorithm
Concept: using words and symbols between natural language and computer language to describe algorithms
Three basic control structures
①Sequential structure: Indicates that the steps in the program are executed in the order in which they appear.
②Selection structure: Indicates that there are branches in the processing steps of the program, and one of the branches needs to be selected for execution based on a specific condition.
Select structure
①Single selection
②Double selection
③Multiple choices
③Loop structure: Indicates that the program repeatedly performs one or more operations until the judgment condition is false (or true) before the loop can be terminated.
Computer Programs and Programming Languages
Computer program
Concept: It refers to the set of instructions that the computer can recognize and run.
commonly used computers
①Arithmetic unit
②Controller
③Memory
④Input device
⑤Output device
computer programming language
①Machine language
②Assembly language
③High-level language
compiled language
Concept: The program is first translated into machine language and an executable file is generated.
Advantages: more optimized code
Disadvantages: Poor platform portability
Typical languages: c, c++...
interpreted language
Concept: The program does not need to be pre-translated to generate an executable file. Every time it is run, it needs to be interpreted and executed statement by statement.
Advantages: Platform migration is easy
Disadvantages: low operating efficiency
Typical languages: Java, Python...
