Set (computer science) Guide, Meaning , Facts, Information and Description
In computer science, the set is a collection of certain values without any particular order. It corresponds with the mathematical concept of set, but with the restriction that it has to be finite. Disregarding sequence, it is the same as a list. A set can be seen as an associative array where the value of each key-value pair is ignored.Sets can be implemented using various data structures. Ideal set data structures make it efficient to check if an object is in the set, as well as enabling other useful operations such as iterating through all the objects in the set, performing a union or intersection of two sets, or taking the complement of a set in some limited domain. Popular methods include arrays, hash tables, and any sort of tree structure. A Bloom map implements a set probabilistically, using a very compact representation but risking false positives on queries.
One of the earliest languages to support sets was Pascal; many languages now include it, whether in the core language or in a standard library. Java programming language offers Set interface to support sets. In C++, STL provides set classeses.
