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.


	fig_width_pt = 246. # Get this from LaTeX using \the\columnwidth
	inches_per_pt = 1.0/72.27 # Convert pt to inch
	golden_mean = (sqrt(5)-1.0)/2.0 # Aesthetic ratio
	fig_width = fig_width_pt*inches_per_pt # width in inches
	fig_height = fig_width*golden_mean#/1.5 # height in inches
	figW = fig_width #*2
	fig_size = [figW,fig_height]
	params = {'backend': 'pdf',
	'axes.labelsize': 12,

	; Two calculations are needed.
	; 1) A reference calcuation without the slab (to get the incident flux)
