What are the basic operations I can perform on sets in Ruby?

In Ruby, you can perform several operations on sets, including union, intersection, difference, and subset checks.

Can you give me an example of how to perform a union operation?

Sure! You can use the | operator or the union method. For example: set1 | set2 or set1.union(set2).

What about intersection? How do I do that?

For intersection, you can use the & operator or the intersection method. For example: set1 & set2 or set1.intersection(set2).

Are there any methods to check if one set is a subset of another?

Yes! You can use the subset? method. For example: set1.subset?(set2) will return true if set1 is a subset of set2.
