A New Implementation for a Fast Hash Table - CodeProject

WebIn computing, a hash table, also known as hash map, is a data structure that implements an associative array or dictionary. It is an abstract data type that maps keys to values. A hash table uses a hash function to compute an index, also called a hash code, into an array of buckets or slots, from which the desired value can be found.During lookup, the … WebThe element is stored in the hash table where it can be quickly retrieved using hashed key. hash = hashfunc (key) index = hash % array_size. In this method, the hash is independent of the array size and it is then reduced … WebA hash table implements an associative array abstract data type that maps keys to values.
