## Simple logging mechanism for Bash

## Author: Michael Wayne Goodman <[email protected]>
## Thanks: Jul for the idea to add a datestring. See:
## http://www.goodmami.org/2011/07/simple-logging-in-bash-scripts/#comment-5854
## Thanks: @gffhcks for noting that inf() and debug() should be swapped,
##         and that critical() used $2 instead of $1

Studying for a Tech Interview Sucks, so Here's a Cheat Sheet to Help

This list is meant to be a both a quick guide and reference for further research into these topics. It's basically a summary of that comp sci course you never took or forgot about, so there's no way it can cover everything in depth. It also will be available as a gist on Github for everyone to edit and add to.

Data Structure Basics

###Array ####Definition:

• Stores data elements based on an sequential, most commonly 0 based, index.
• Based on tuples from set theory.
