Introduction to Hashing

Introduction to Hashing. CS 311 Winter, 2013. Dictionary Structure. A dictionary structure has the form: (Key, Data) Dictionary structures are organized in a manner that optimizes search time for the key. Hashing stores dictionary objects in a table where each location has an address.
