Hashopoly

Objectives

1. Build simple hashes.
2. Build nested hashes.
3. Access and modify data stored in a hash.
4. Add new data to a hash.

Instructions

The series of tests will require you to build methods that build up a nested hash, one layer (or "level") at a time, in a similar way to how we built our epic_tragedy hash in the previous lesson. Read the test output very carefully; it will guide you through building the necessary methods. Don't forget to return the hash, if necessary! At the end of the exercise, your multidimensional monopoly hash should look like this:

monopoly =  {
  :railroads=>
  {
    :pieces=>4,
    :rent_in_dollars=>
    {
      :one_piece_owned=>25,
      :two_pieces_owned=>50,
      :three_pieces_owned=>100,
      :four_pieces_owned=>200
    },
    :names=>
    {
      :reading_railroad=>
      {
        "mortgage_value"=>"$100"
      },
      :pennsylvania_railroad=>
      {
        "mortgage_value"=>"$200"
      },
      :b_and_o_railroad=>
      {
        "mortgage_value"=>"$400"
      },
      :shortline=>
      {
        "mortgage_value"=>"$800"
      }
    }
  }
}

Don't Forget!

Remember that you can use binding.pry to help you get inside your methods and understand what is going on if you need to debug. Remember to google questions that you have if you get stuck!
