WebThe main idea behind the hashing is to create the (key/value) pairs. If the key is given, then the algorithm computes the index at which the value would be stored. It can be written as: Index = hash (key) There are three ways of calculating the hash function: Division method Folding method Mid square method WebHashing is a technique of mapping a large set of arbitrary data to tabular indexes using a hash function. It is a method for representing dictionaries for large datasets. It allows lookups, updating and retrieval operation to occur in a constant time i.e. O(1).
