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.

README

This gist assumes you are migrating an existing site for www.example.com — ideally WordPress — to a new server — ideally Ubuntu Server 16.04 LTS — and wish to enable HTTP/2 (backwards compatibile with HTTP/1.1) with always-on HTTPS, caching, compression, and more. Although these instructions are geared towards WordPress, they should be trivially extensible to other PHP frameworks, other FastCGI backends, and even non-FastCGI backends (using proxy in lieu of fastcgi in the terminal Caddyfile stanza).

Quickstart: Use your own naked and canonical domain names instead of example.com and www.example.com and customize the Caddyfile and VCL provided in this gist to your preferences!

These instructions target Varnish Cache 4.1, PHP-FPM 7.0, and Caddy 0.10. (I'm using MariaDB 10.1 as well, but that's not relevant to this guide.)

	#### Exercises

	1. Define and compare recursion and iteration.

	Recursion is a procedure that calls itself until a certain condition (base case) is reached. Recursive solutions can be slower and are subjected to system limitations

	Iteration is a procedure that uses loop to repeat a process. Iterative solutions may be harder to implement.


	2. Name five algorithms that are commonly implemented by recursion.
