HashSet
A HashSet is a collection that stores unique elements and uses hashing for fast lookups, insertions and deletions. It does not maintain element order and allows null values (in some languages). Ideal for removing duplicates and quick membership tests, HashSet offers average O(1) time complexity for basic operations.
