WebHeap I think of as a category of implementation that generally guarantees not only the same interface, but also same access times. You see this with associative maps, and hash tables and binary search trees as well. Bsts and hash tables are both concrete data structures that provide the associative map abstract interface. 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, ….

WebHash tables are a type of data structure in which the address/ index value of the data element is generated from a hash function. This enables very fast data access as the index value behaves as a key for the data value. In other words, hash tables store key-value pairs but the key is generated through a hashing function.
