How Hashing is useful in Recent Technologies? Illustration with its applications.
What is Hashing? Hashing is a technique or process of mapping keys, values into the hash table by using a hash function. It is done for faster access to elements. The efficiency of mapping depends on the efficiency of the hash function used. Hashing is also known as Hashing Algorithm or Message Digest Function. It is a technique to convert a range of key values into a range of indexes of an array. Hashing is one of the searching techniques that use constant time. The time complexity in hashing is O(1). What is Hash Function? A hash function is a function that takes a set of inputs of any arbitrary size and fits them into a table or other data structure that contains fixed-size elements. · A fixed process that converts a key to a hash key is known as a Hash Function. · This function takes a key and maps it to a value of a certain length whic...
