What is a hash table?

A hash table, or a hash map, is a data structure used in computer science to store and retrieve values based on a unique key. Hash tables offer an efficient implementation method for associative arrays or dictionaries, which involve storing data in the form of key-value pairs. The primary idea behind a hash table is to use a hash function to map keys to indices in an array, allowing for quick retrieval of values associated with those keys.Click Here
