hashsets
A HashSet is a data structure in computer science that implements the mathematical concept of a set. It is designed to store unique elements and provide efficient methods for adding, removing, and checking for the presence of elements. HashSets are typically implemented using a hash table, which allows for average-case constant time complexity for these operations.
The primary advantage of a HashSet is its ability to quickly determine whether an element is present
HashSets are commonly used in various applications, including database indexing, caching, and implementing sets in programming
In some programming languages, such as Java and Python, HashSets are provided as built-in data structures. These
Overall, HashSets are a fundamental data structure in computer science, offering a balance between performance and
