Programming and Data Structures for Computer Science Exams

Preparing for highly competitive computer science and IT exams requires a rock-solid understanding of how data is stored, organized, and manipulated. This text-based course is designed to take you from core programming fundamentals to the complex data structures that form the backbone of modern software engineering and technical assessments. You will build the problem-solving intuition needed to analyze efficiency and write clean, structured code. By working through clear written explanations, practical code implementations, and structured exercises, you will transition from memorizing syntax to deeply understanding algorithmic design. What you'll learn: Understand core programming concepts including variables, control flow, functions, and recursion; Implement foundational data structures such as arrays, linked lists, stacks, and queues from scratch; Analyze algorithm performance using Big O notation to determine time and space complexity; Master advanced structures including binary trees, heaps, and hash tables; Apply sorting and searching algorithms to solve complex data manipulation problems; Practice tracing code execution step-by-step to debug logical errors and optimize performance. The course begins with a thorough introduction to basic programming terminology and memory management before advancing systematically through linear and non-linear data structures. This course is designed specifically for beginners, aspiring software engineers, and students preparing for academic or professional computer science examinations, with no prior advanced programming experience required.
