Answer 1

Maybe a simpler option since I imagine you are looking for help with a solution to a Hacker Rank question? The addition of limits made it simpler for me to debug where the issue was with the returned error.

SELECT city, length(city) FROM station order by length(city) desc limit 1;

SELECT city, length(city) FROM station order by length(city) asc, city asc limit 1
