Even if you create the same function, the code of a junior developer who has just learned JavaScript syntax and that of an experienced senior developer will be quite different. Of course, even if the results are the same. The reason the latter's code is recognized is because of its well-designed structure and scalability to respond to changes. This lecture will learn about how to create such good code.

We provide CodeTree past exam questions along with algorithms and tips for solving them. Although C++ is used, the course is accessible to those using other languages as it does not rely on libraries. (Python code is provided)
