The Feynman Technique, developed by Nobel Prize-winning physicist Richard Feynman, breaks down complex ideas by explaining them in plain language.Code quality is based on three main pillars: complexity, errors, and readability.Complexity measures the intricate logic in code, while errors include syntax errors, logical errors, runtime errors, and time limit exceeded issues.Readability focuses on the ease of understanding by others, which includes factors like naming, formatting, structure, and comments.
