Primitive recursive function

A **primitive recursive function** is a type of function defined using a limited set of basic functions and a specific set of operations. Primitive recursive functions are important in mathematical logic and computability theory, as they represent a class of functions that can be computed effectively. The core concepts regarding primitive recursive functions include: 1. **Basic Functions**: The basic primitive recursive functions include: - **Zero Function**: \( Z(n) = 0 \) for all \( n \).
