Solution
It seems like you're asking for a SQL query. Here's how you can do it:
SELECT DISTINCT CITY
FROM STATION
WHERE CITY REGEXP '^[aeiou].*[aeiou]$';
Here's the step by step explanation:
-
SELECT DISTINCT CITY FROM STATION: This part of the query selects all unique city names from the tableSTATION. -
WHERE CITY REGEXP '^[aeiou].*[aeiou]$': This is the condition that filters the cities. TheREGEXPfunction is used to match a regular expression pattern. -
'^[aeiou].*[aeiou]$': This is the regular expression pattern.^indicates the start of the string,[aeiou]matches any vowel,.*matches any character (.) any number of times (*), and$indicates the end of the string. So this pattern matches any city name that starts and ends with a vowel.
Please note that SQL syntax may vary slightly depending on the specific SQL variant you're using. The above query is written in MySQL. If you're using a different SQL variant, you may need to adjust the syntax accordingly.
