hash table is a data structure that maps keys to values. The keys are distributed across a number of buckets by hashing the key to produce a bucket index. good hash function produces an even distribution across all the buckets so that no bucket is overloaded.

The key and the value can be any type of data structure. Hash function; Mapping is from key -> hash code -> index (hash code != index) Collisions: Possible for the same key to map to the same hash code, and two different hash codes can map to the same index.

Queues are a first in, first out (FIFO) data structure. Made with a linked list that only removes from head and adds to tail. Stores data with key value pairs. Hash functions accept a key and return an output unique only to that specific key.

Stores data elements based on an sequential, most commonly 0 based, index. - Based on [tuples] (http://en.wikipedia.org/wiki/Tuple) from set theory. - They are one of the oldest, most …
