Set Class in Ruby 💎

In Ruby, the Set class is a collection of unique values that maintains only distinct elements and supports set operations like union, intersection, and difference. To use a Set, require the "set" library and create a new instance with an array of values, which can then be added to or operated on. Sets can also be converted from arrays, eliminating duplicates, and are particularly useful when needing to eliminate duplicates, perform set operations, or make efficient membership checks. Sets are similar to arrays but with no duplicates allowed, and are useful in specific scenarios where uniqueness is essential.
