Building Nested Hashes Lab

Learning Goals

• Build a nested hash
• Add key/value pairs in a nested hash
• Update key/value pairs in a nested hash

Introduction

In this lab, we will practice constructing a deeply nested hash.

Instructions

You are tasked with building 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. 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"
      }
    }
  }
}
