Web1. Division Method. If k is a key and m is the size of the hash table, the hash function h () is calculated as: h (k) = k mod m. For example, If the size of a hash table is 10 and k = 112 then h (k) = 112 mod 10 = 2. The value of m must not be the powers of 2. This is because the powers of 2 in binary format are 10, 100, 1000, …. WebIn computing, a hash table, also known as hash map, is a data structure that implements an associative array or dictionary.
