WebSTATIC HASHING As shown in the above example, a table stores a value that can be retrieved by a key that is not necessarily an integer. This key, logically, is the ‘location’ of the value. Associative look-up like this can be implemented with a static hashing algo-rithm (Reference 6, pp. 506–549). For an open hash table, the data ...
