# Hash Table

`Hash Table` is a data structure which organizes data using `hash functions` in order to support quick insertion and search.

There are two different kinds of hash tables:- **Hash set** and **Hash map.**

* The `hash set` is one of the implementations of a `set` data structure to store `no repeated values`.
* The `hash map` is one of the implementations of a `map` data structure to store `(key, value)` pairs.
