This is where the "self-calling" happens. In this step, the function calls itself but with a slightly modified input that moves the problem closer to the base case. A Real-World Analogy
Every valid recursive function must have two essential components to function correctly: Introduction to Recursive Programming
You reach the smallest doll that cannot be opened. You’ve found the center and the process stops. Why Use Recursion? This is where the "self-calling" happens
Think of a set of (Russian nesting dolls). If you want to find the tiny charm hidden in the very center, the process is recursive: You’ve found the center and the process stops
At its core, is a method of problem-solving where a function calls itself to solve smaller versions of the same problem. To a beginner, this might sound like a recipe for an infinite loop, but when applied correctly, it is one of the most elegant and powerful tools in a programmer’s toolkit. It allows us to take complex, repetitive tasks and distill them into a few lines of clean, readable code. The Anatomy of Recursion
