Master the art of recursive thinking through interactive visualizations. Watch how functions call themselves to solve complex problems elegantly.
Recursion is a programming technique where a function calls itself to solve smaller instances of the same problem.
The terminating condition that stops the recursion. Every recursive function must have at least one base case.
The function calls itself with modified parameters, working towards the base case.
Each recursive call is added to the call stack and resolved in reverse order (LIFO - Last In, First Out).
Start with simple examples and progress to complex problem-solving patterns
