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/sh

# Git pre-commit hook that prevents accidentally committing things that shouldn't be, like:
#
#   * ":focus", used with RSpec/Guard
#   * "show_page", used to debug request specs
#   * "console.log" or "console.debug", used in JavaScript debugging
#   * "DO NOT COMMIT!" comments

# Modify the regexps to suit your needs. The error message shows the full regexp match,

# Write a bash script named "hw22-3" that accepts a list of inode numbers from the command line,
#     and displays
#     the file name and physical file system of each file with that inode number.  If no
#     file exists with that inode number display "no such file".

#     EXAMPLE:
#               > hw22-3 8384567 12345
#                 Inode "8384567" has files:
