What is recersion?

Answer 1

Recursion is a programming technique in which a function calls itself in order to solve a problem. It typically involves a base case that terminates the recursive calls and a recursive case that breaks the problem into smaller, more manageable subproblems. This method is often used to simplify complex tasks, such as traversing data structures or solving mathematical problems like factorials and Fibonacci sequences. Properly implemented recursion can lead to elegant and concise solutions, but it requires careful handling to avoid issues like infinite loops or excessive memory use.
