What are sets in Ruby and how do they ensure uniqueness?

Can you explain what sets are in Ruby?

Sure! In Ruby, a set is a collection of unordered values that are unique, meaning no duplicates are allowed.

How do sets ensure that all elements are unique?

Sets use a hash table internally to track elements, so when you try to add a duplicate, it simply ignores it.

Can you show me an example of using sets in Ruby?

Of course! Here's a simple example: require 'set'; my_set = Set.new([1, 2, 2, 3]); puts my_set.inspect will output #<Set: {1, 2, 3}>.

What happens if I try to add a duplicate value?

If you try to add a duplicate, the set will remain unchanged, keeping only unique values.
