Detailed explanation1: Hashing in the data structure is a technique of mapping a large chunk of data into small tables using a hashing function. It is also known as the message digest function. It is a technique that uniquely identifies a specific item from a collection of similar items.
Detailed explanation2: Hashing is the process of transforming any given key or a string of characters into another value. This is usually represented by a shorter, fixedlength value or key that represents and makes it easier to find or employ the original string. The most popular use for hashing is the implementation of hash tables.
Detailed explanation3: Hashing is one of the searching techniques that uses a constant time. The time complexity in hashing is O(1). Till now, we read the two techniques for searching, i.e., linear search and binary search. The worst time complexity in linear search is O(n), and O(logn) in binary search.
Detailed explanation4: Unlike other searching techniques, Hashing is extremely efficient. The time taken by it to perform the search does not depend upon the total number of elements. It completes the search with constant time complexity O(1).
