Bioinformatics Algorithms: Solving the Coin Change Problem with Recursion

Understanding how algorithms solve complex optimization problems is a fundamental skill for modern bioinformatics. Recursive thinking allows us to break down massive biological data challenges, such as sequence comparison, into manageable, repeating subproblems. This text-only course guides you through the core concepts of recursion by solving the classic coin change problem. You will learn to write clean, structured code, analyze algorithmic efficiency, and understand how these computational models map directly to real-world biological sequence analysis. What you'll learn: Understand the foundational principles of recursion, call stacks, and base cases; Solve the coin change problem step-by-step using recursive logic; Apply modern Python type hints to build readable and maintainable algorithmic code; Analyze the time and space complexity of recursive solutions using Big O notation; Implement basic memoization to optimize recursive performance and prevent redundant calculations; Connect the logic of the coin change problem to sequence alignment techniques in bioinformatics. You will start with basic algorithmic definitions and structural concepts before moving on to hands-on recursive implementations, optimization strategies, and biological applications. This course is designed for beginners in computer science and bioinformatics, requiring no prior advanced mathematical background.
