felsorolhatónak

Felsorolhatónak is a Hungarian adjective that translates to "enumerable" or "listable" in English. It describes something that can be listed or enumerated, meaning its individual elements can be counted or written down in a sequence. This concept is particularly relevant in mathematics and computer science.

In mathematics, an enumerable set is a set whose elements can be put into a one-to-one correspondence with the set of natural numbers. This means that even if the set is infinite, its elements can be systematically listed. Such sets are also known as countably infinite sets. For example, the set of integers is enumerable because we can list them as 0, 1, -1, 2, -2, and so on.

In computer science, the term "enumerable" often refers to data types that have a finite, fixed set of named constants. These are commonly known as enumerations or enums. In programming languages, an enumeration allows a developer to define a type that can hold one of a predefined set of values, making the code more readable and less prone to errors. For instance, a day of the week could be an enumerable type with values like Monday, Tuesday, Wednesday, etc. The key characteristic is that each possible value can be explicitly listed and identified.
