## Avi's Solution ##
organized_pigeon_data = {}

pigeon_data.each do |property, value_hash|
  value_hash.each do |value, birds|
    birds.each do |name|
      if organized_pigeon_data[name]
        if organized_pigeon_data[name][property]
          organized_pigeon_data[name][property] << value
        else
          organized_pigeon_data[name][property] = [value]
        end
      else  
        organized_pigeon_data[name] = {property => value}
      end
    end
  end
end

raise organized_pigeon_data.inspect


# ## David's Solution ##
# pigeon_data.each_pair do |attribute_name, attribute_hash|
#       attribute_hash.each_pair do |attribute, name_list|
#         name_list.each do |name|
#           p attribute_name #why?
#           p attribute
#           p name
#           pigeon_list[name] ||= {}
#           pigeon_list[name][attribute_name] ||= []
#           pigeon_list[name][attribute_name] << attribute.to_s
#         end
#       end
#     end


## My Solution ##
# # collect_names(pigeon_data)
#   names = []
#   pigeon_data.each do | attribute, attrib_array | 
#     attrib_array.each do | property, name| 
#       names << name 
#     end
#   end
#   names.flatten.uniq!


# # create_list(names, pigeon_data)
# pigeon_list = {}
# names.each do |name|
#   pigeon_list[name] = { :color => [], :gender => "", :lives => ""}
#   pigeon_data.each do | attribute, attrib_array |
#     attrib_array.each do | property, pigeons |
#       pigeon_list[name][attribute] << property if pigeons.include?(name)
#     end
#   end
#   pigeon_list  
# end

# puts "#{pigeon_list}"


# 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 match 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 => "City Hall"
#   },
#   "Ms .K" => {
#     :color => ["grey", "white"],
#     :gender => "female",
#     :lives => "Central Park"
#   },
#   "Queenie" => {
#     :color => ["white", "brown"],
#     :gender => "female",
#     :lives => "Subway"
#   },
#   "Andrew" => {
#     :color => ["white"],
#     :gender => "male",
#     :lives => "Central Park"
#   },
#   "Alex" => {
#     :color => ["white", "brown"],
#     :gender => "male",
#     :lives => "Central Park"
#   }
# }
