   What is a hash function?

   • A hash function is a function that takes an input (or ‘message’) and returns a fixed-size string of bytes. The output, typically a number, is called the hash code or hash value. The main purpose of a hash function is to efficiently map data of arbitrary size to fixed-size values, which are often used as indexes in hash tables.

   How does a hash table work?

   • Hash Table: Hash table is a data structure that maps keys to values using a special function called a hash function. Hash stores the data in an associative manner in an array where each data value has its own unique index. How does Hashing work? Suppose we have a set of strings {“ab”, “cd”, “efg”} and we would like to store it in a table.
