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.

<div class="col-md-8 col-md-offset-1">
  <div class="panel panel-default">
    <%= form_for(@weekly_performance_review) do |f| %>
      <% if @weekly_performance_review.errors.any? %>
        <div id="error_explanation">
          <h2><%= pluralize(@weekly_performance_review.errors.count, "error") %> prohibited this weekly_performance_review from being saved:</h2>

          <ul>
          <% @weekly_performance_review.errors.full_messages.each do |message| %>
            <li><%= message %></li>

do ($ = jQuery, exports = window) ->

  class ActiveDataBinder
    constructor: (uid) ->

      # Use a jQuery object as simple PubSub

      pubSub = $ {}

      # We expect a 'data' attribute specifying the binding

Template Components

Used to provide structural templates.

# Simple bijective function
#   Basically encodes any integer into a base(n) string,
#     where n is ALPHABET.length.
#   Based on pseudocode from http://stackoverflow.com/questions/742013/how-to-code-a-url-shortener/742047#742047

ALPHABET =
  "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789".split(//)
  # make your own alphabet using:
  # (('a'..'z').to_a + ('A'..'Z').to_a + (0..9).to_a).shuffle.join
