Recursion

Recursion is a method in mathematics and computer science where a function, process, or definition refers to itself directly or indirectly. It is commonly used to solve problems by breaking them down into simpler, smaller instances of the same problem. In programming, recursive functions call themselves with modified parameters until reaching a base case, which stops further calls. Recursion is fundamental in algorithms for tasks such as sorting, searching, and traversing data structures like trees and graphs.
