Coding Test Basics in 2 Hours (Python, C++, Java, Javascript)

A coding test lecture taught by a world competition finalist! Now, stop solving by intuition and start solving with confidence!

This course is for those who want to prepare for coding tests in the form of real mock exams. Each mock exam consists of 5 questions. It would be good to take my course, "Algorithm Problem Solving for IT Employment".

The fastest way to build the foundation of coding tests for joining IT companies! #Picture-based explanation #Code writing know-how #Companies you can go to #Only necessary questions

Asynchronous programming is a core concept in JavaScript. This course will help you fully understand and use asynchronous programming.

When learning Swift, the iOS programming language, it can be confusing when multiple concepts appear all at once. That's why I created this course with the principle that "when understanding a new concept, only previously learned concepts should be used." So this course is meticulously designed with a sequential structure between concepts, where only one new concept appears at each stage, and no other unfamiliar concepts appear at all. One concept per minute, 180 concepts total. From the basics of variables and constants to understanding memory structure from a CS perspective, and even the latest syntax for asynchronous processing. In 3 hours, you'll learn 180 core concepts in the designed order.

Theory, numerical approximations, intuition, and visualization in integral calculus. Enhance your math-coding skills.

Through training in thinking, expressing, and coding, you can easily understand and approach Java programming. You can understand the relationship between programming elements and gain confidence in future Java API utilization and projects through precise concept organization of object-oriented programming.

This course is a video lecture that systematically covers the core modern JavaScript syntax essential for learning React.js and Vue.js frontend development. It is structured to help you develop efficient coding skills through ES6+ syntax, latest features, and practical examples that can be directly applied to work and learning.

Modern C++ Programming based on Object-Oriented Concepts for Computer Science Majors

Learn the essential modern Java technologies of Lambda, Stream, and functional programming with Java, from the basics to the practical level, in depth.

This course goes beyond simple grammar explanations and focuses on developing C++ programming skills that can be applied immediately in the field. Throughout my teaching, I have directly addressed common challenges faced by many learners—such as struggling to understand the STL or feeling confused by file handling and exception handling concepts. Based on this experience, I provide step-by-step explanations to ensure even complex concepts are understood easily and clearly. Furthermore, this course is not just about delivering theory; it is structured around: 👉 "Why this concept is necessary" 👉 "How it is used in actual code" 👉 "How it is applied in professional practice"

This course allows you to learn C and C++ at the same time. It will be helpful for beginners to programming or those who want to learn C or C++ for the first time.

✅ This is the (0) intro lecture that introduces the entire series from (1) to (6). ✅ It explains NVIDIA GPU + CUDA programming step-by-step from the basics. ✅ Use C++/C to process arrays, matrices, image processing, statistical processing, and sorting extremely fast through parallel computing.

Even office workers who know nothing about coding can easily learn the basic concepts and grammar of programming through practice, and learn file input/output, Excel data processing, automatic creation of MS-Word documents, graph drawing, web scraping, etc.

It would be efficient to automate IT security tasks using Python, wouldn't it? This course follows hands-on practice, applying Python and web Flask development to automate tasks, idea by idea.

This is an introductory Java course designed so that even those starting programming for the first time can follow along. You will systematically learn everything from JDK 21 environment configuration to variables, data types, control flow statements, arrays, strings, and the core concepts of Object-Oriented Programming (OOP) such as classes, inheritance, polymorphism, and exception handling. Rather than simply listing syntax, we explain "why it works this way" to help you build a solid foundation.

This is a JavaScript course designed to help you become a top-tier web developer through in-depth lessons. By completing the course, you will gain a deep understanding of the essence of JavaScript, allowing you to become an expert in React and Next.js, which you will learn next.

From the basics of Numpy and Pandas to data preprocessing, visualization, and crawling, all in one place! This is an introductory Python course for data analysis.

Through this course, you can learn how to run Java applications more efficiently and effectively solve performance issues that may arise.

Anyone who is a C/C++ developer can get started. You can quickly learn MFC Windows programming by selecting only the core. We also provide a 1200-page textbook.
