# Ruby problem exercise from: http://www.rubeque.com/problems/a-man-comma--a-plan-comma--a-canal--panama-excl-

# We've covered the above problem at Brainstation Toronto: Backend Programming - First Cohort. (http://brainstation.it)

# The following solution is O(N^2)
# I've deliberately kept is as such (O(N^2)) so as to make sure 
# It's easier to explain to the students.

  str == str.reverse

Let's build a Recent File Tracker

• Implement a Class, name it RecentFiles

• You can start implementing your class from 2nd line onwards.

• You can run the test code, which will test your code using the following command: rspec file_name.rb

• You can replace the file_name.rb with your actual file which you are working with.

• If you get any errors such as rspec not found etc, please do: sudo gem install rspec

• The class should be able to handle the following scenarios:

  • Output a list of most recent accessed files.

    click_link('Link Text')
    click_button('Save')
    click('Link Text') # Click either a link or a button

File & Directory Classes:

• http://ruby-doc.org/core-2.2.0/Dir.html

• http://ruby-doc.org/core-2.2.0/File.html

• http://ruby-doc.org/core-2.2.0/File.html#method-c-directory-3F

• Loop Recursively Until no Directories are left to loop over.

• Use File.read to read the YML file one at a time.

• require 'yaml' module to start using it.

• Use the YAML module's load method to convert the YAML into a Ruby data structure, ie: Hash
