👉 In mathematics, a perfectator is a mathematical function that is defined only for positive integers. It represents the "best possible" value for a given input under some conditions or constraints. For example: f(n) = n^2 if n is an even number f(n) = -n + 1 if n is odd and greater than 1 This means that f(n) will be positive for all positive integers, but it will be negative for all odd integers greater than 1
