A hash function is any function that can be used to map data of arbitrary size to fixed-size values. The values returned by a hash function are called hash values, hash codes, digests, or simply hashes. The values are usually used to index a fixed-size table called a hash table.

What is hashing with example?

Hashing is an important data structure designed to solve the problem of efficiently finding and storing data in an array. For example, if you have a list of 20000 numbers, and you have given a number to search in that list- you will scan each number in the list until you find a match.

What is hashing in simple terms?

Hashing is the process of converting a given key into another value. ... The result of a hash function is known as a hash value or simply, a hash. A good hash function uses a one-way hashing algorithm, or in other words, the hash cannot be converted back into the original key.
