A recursive process is a method where a solution to a problem depends on solutions to smaller instances of the same problem. This approach is often used in computer science and mathematics, where a function calls itself to break down complex tasks into simpler ones. For example, calculating the factorial of a number can be done recursively by multiplying the number by the factorial of the number minus one. In programming, recursive processes can simplify code and make it easier to read. However, they can also lead to performance issues if not managed properly, such as excessive memory use or infinite loops. Understanding recursion is essential for working with algorithms and data structures, such as trees and graphs.
