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.

hunj

# path_strip(input_file, domain, output_file)
# imports an xml file containing paths of the website's pages,
# strips all unnecessary strings except for the path of the pages.
## Parameters:
# +input_file+ name of the input xml file
# +domain+ the domain of the URL to exclude in the result
# +output_file+ name of the output file, ending in .csv (preferred)
def path_strip(input_file, domain, output_file)
  raise "domain must be string form" unless domain.is_a? String
  raise "invalid input file name" unless input_file.is_a? String

def path_strip(input_file, domain, output_file)
  raise "domain must be string form" unless domain.is_a? String
  raise "invalid input file name" unless input_file.is_a? String
  raise "invalid output file name" unless output_file.is_a? String

  file = File.open(input_file, "r")
  data = file.read
  file.close
  data_lines = data.lines
