-- write a SQL query to find the 50 players paid the least in 2001.
--     Sort players by salary, lowest to highest.
--     If two players have the same salary, sort alphabetically by first name and then by last name.
--     If two players have the same first and last name, sort by player ID.
--     Your query should return three columns, one for players’ first names, one for their last names, and one for their salaries.
