Chapter 24: Lookup Tables and Hashing

(IV Standard Data Structures, V Standard Algorithms)

Name a way to retrieve data faster than a binary search. a lookup or hash table

  1. Explain how lookup tables work.


  1. List the properties of a good hash table


  1. State the 2 principle ways of avoiding collisions with a hash table.

Check out Articles by Mr. Rogers:

Insultingly Stupid Movie Physics is one of the most humorous, entertaining, and readable physics books available, yet is filled with all kinds of useful content and clear explanations for high school, 1st semester college physics students, and film buffs.

It explains all 3 of Newton's laws, the 1st and 2nd laws of thermodynamics, momentum, energy, gravity, circular motion and a host of other topics all through the lens of Hollywood movies using Star Trek and numerous other films.

If you want to learn how to think physics and have a lot of fun in the process, this is the book for you!
