| CITY        | VARCHAR(21)|

 Write a query to print shortest and longest cities name. If there are more than one cities print lexicographical smallest name.

>>(select CITY, char_length(CITY) as len_city from STATION order by len_city limit 1) union all (select CITY, char_length(CITY) as len_city from STATION order by len_city desc limit 1) order by len_city;

Thanks.
