 - Alphabetically list all of the country codes in the continent_map table that appear more than once. Display any values where country_code is null as country_code = "FOO" and make this row appear first in the list, even though it should alphabetically sort to the middle. Provide the results of this query as your answer.
 
 - For all countries that have multiple rows in the continent_map table, delete all multiple records leaving only the 1 record per country. The record that you keep should be the first one when sorted by the continent_code alphabetically ascending. Provide the query/ies and explanation of step(s) that you follow to delete these records.
