Hash tables use a hash function to compute an index into an array where the element will be inserted or searched. By using a good hash function, hashing can perform extremely well. WebA hash table is a data structure that stores unordered items by mapping (or hashing) each item to a location in an array (or vector). Ex: Given an array with indices 0..9 to store integers from 0..500, the modulo (remainder) operator can be used to map 25 to index 5 (25 % 10 = 5), and 149 to index 9 (149 % 10 = 9).
