Data structure create new empty set

In many programming languages, you can create a new empty set using the following syntax:

Python:

my_set = set()

Java:

Set<String> mySet = new HashSet<>();

C++:

std::set<int> mySet;

JavaScript:

const mySet = new Set();

C#:

HashSet<int> mySet = new HashSet<int>();

Ruby:

my_set = Set.new

Swift:

var mySet: Set<Int> = []

Note that in some languages, such as Python and JavaScript, the set data structure is a built-in type, while in others, such as Java and C#, you need to import a specific library or use a specific class to create a set.

Also, in some languages, you can create an empty set using a specific constructor or method, such as Set() in Python or HashSet<int>() in C#.
