Sets
In Ruby, a set is a collection of unique elements, meaning each element appears only once in the set. Sets are useful for tasks where you need to ensure uniqueness or perform set operations like union, intersection, and difference.
Ruby provides the Set class in the standard library to work with sets. You can create a set using the Set.new method and perform various set operations using built-in methods like union, intersect, and difference.
Below is the Ruby program to implement sets:
require 'set'
# Creating sets
set1 = Set.new([1, 2, 3, 4, 5])
set2 = Set.new([4, 5, 6, 7, 8])
# Union of sets
union_set = set1.union(set2)
puts union_set.inspect # => #<Set: {1, 2, 3, 4, 5, 6, 7, 8}>
# Intersection of sets
intersection_set = set1.intersection(set2)
puts intersection_set.inspect # => #<Set: {4, 5}>
# Difference of sets
difference_set = set1.difference(set2)
puts difference_set.inspect # => #<Set: {1, 2, 3}>

How to Implement Data Structures in Ruby?
Data structures are fundamental components of any programming language, allowing developers to organize and manipulate data efficiently. In Ruby, a versatile and expressive language, implementing various data structures is straightforward. In this article, we’ll explore how to implement common data structures such as arrays, linked lists, stacks, queues, trees, graphs, and hashmaps in Ruby. The article focuses on discussing data structures in Ruby.
