 I often encounter students intrigued by the concept of recursion. It’s one of those topics in computer science that can seem daunting at first, but once understood, it becomes a powerful tool for solving problems.  I’ll break down recursion in simple terms, explain how it works, and highlight its importance in programming. Recursion, in programming, occurs when a function calls itself to solve a problem. The idea behind recursion is to break down complex problems into simpler, more manageable sub-problems. This approach is especially useful when a problem can be divided into smaller versions of itself. For example, consider a problem where you need to calculate the factorial of a number. Factorial, by definition, is the product of an integer and all the integers below it. A recursive solution would break this problem into smaller steps until the simplest case (the base case) is reached. Let’s take a quick look at how recursion works. How Does Recursion Work? Recursion follows...
