A **primitive recursive set function** is a concept from mathematical logic and theoretical computer science, particularly in the theory of computable functions. It refers to a function defined using a specific class of functions that are called primitive recursive functions. \#\#\# Primitive Recursive Functions Primitive recursive functions are a subset of total functions from natural numbers to natural numbers. They include basic functions such as: 1. **Zero Function**: \\( Z(n) = 0 \\) for all \\( n \\).
