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.

	#!/bin/bash

	docker_version_regex='^(1\.[4-8]\.)'
	docker_version=`docker --version \| awk '{print \$3}'`
	log_directory='/logs'
	log_file="$log_directory"/cleanup.log

	if [ ! -d "$log_directory" ]; then
	mkdir "$log_directory"
	fi

	#!/bin/bash
	mkdir -p /opt/bin
	curl -L `curl -s https://api.github.com/repos/docker/compose/releases/latest \| jq -r '.assets[].browser_download_url \| select(contains("Linux") and contains("x86_64"))'` > /opt/bin/docker-compose
	chmod +x /opt/bin/docker-compose

	package main

	import (
	"fmt"
