   What are the different types of hash functions?

   • The primary types of hash functions are: Division Method. Mid Square Method. Folding Method. Multiplication Method. The easiest and quickest way to create a hash value is through division. The k-value is divided by M in this hash function, and the result is used. h (K) = k mod M (where k = key value and M = the size of the hash table)

   What is a hash table?

   • A hash table is also known as a hash map. It is a data structure that stores key-value pairs. It uses a hash function to map keys to a fixed-size array, called a hash table. This allows in faster search, insertion, and deletion operations. The hash function is a function that takes a key and returns an index into the hash table.

   How should a hash function be designed?

   • The hash function should be designed so that different input values produce different hash values, and small changes in the input produce large changes in the output. Output: The hash value is returned, which is used as an index to store or retrieve data in a data structure.
