👉 In mathematics and computer science, a zoned is a type of function that can be defined on a set with a binary relation. A "zoned" function is one where it has a unique domain (the set over which it takes values) and a unique codomain (the set for which the function returns values). This means that if you define a zoned function, then there must exist at least one element of the codomain for which the function always returns that element.
