NYC Pigeon Organizer

Objectives

1. Understand Hashes and Nesting
2. Work on Sorting Hashes and manipulating nested data structures.

Instructions

You are given the following collected data on New York City pigeons in the form of a hash.

pigeon_data = {
  :color => {
    :purple => ["Theo", "Peter Jr.", "Lucky"],
    :grey => ["Theo", "Peter Jr.", "Ms. K"],
    :white => ["Queenie", "Andrew", "Ms. K", "Alex"],
    :brown => ["Queenie", "Alex"]
  },
  :gender => {
    :male => ["Alex", "Theo", "Peter Jr.", "Andrew", "Lucky"],
    :female => ["Queenie", "Ms. K"]
  },
  :lives => {
    "Subway" => ["Theo", "Queenie"],
    "Central Park" => ["Alex", "Ms. K", "Lucky"],
    "Library" => ["Peter Jr."],
    "City Hall" => ["Andrew"]
  }
}

Iterate over the hash above, collecting each pigeon by name and insert it as the key of a new hash where each name holds the attributes for that bird. Your output should look something like the hash below:

pigeon_list = {
  "Theo" => {
    :color => ["purple", "grey"],
    :gender => ["male"],
    :lives => ["Subway"]
  },
  "Peter Jr." => {
    :color => ["purple", "grey"],
    :gender => ["male"],
    :lives => ["Library"]
  },
  "Lucky" => {
    :color => ["purple"],
    :gender => ["male"],
    :lives => ["Central Park"]
  },
  "Ms. K" => {
    :color => ["grey", "white"],
    :gender => ["female"],
    :lives => ["Central Park"]
  },
  "Queenie" => {
    :color => ["white", "brown"],
    :gender => ["female"],
    :lives => ["Subway"]
  },
  "Andrew" => {
    :color => ["white"],
    :gender => ["male"],
    :lives => ["City Hall"]
  },
  "Alex" => {
    :color => ["white", "brown"],
    :gender => ["male"],
    :lives => ["Central Park"]
  }
}
