    This is in Oracle SQL without REGEX using only basic SELECT statements. It's easy to read. Hope it helps.

    SELECT city
FROM station
WHERE (
   LOWER(city) LIKE 'a%' 
   OR LOWER(city) LIKE 'e%' 
   OR LOWER(city) LIKE 'i%' 
   OR LOWER(city) LIKE 'o%' 
   OR LOWER(city) LIKE 'u%'
)
AND (
   LOWER(city) LIKE '%a' 
   OR LOWER(city) like '%e' 
   OR LOWER(city) LIKE '%i' 
   OR LOWER(city) LIKE '%o' 
   OR LOWER(city) LIKE '%u'
);

    Here is Oracle solution from my HackerrankPractice repository:

    SELECT DISTINCT CITY
FROM STATION
WHERE REGEXP_LIKE(City, '^[AEIOU].*[aeiou]$');

    Feel free to ask if you have any questions :)
