Query the list of CITY names starting with vowels (i.e., a, e, i, o, or u) from STATION. Your result cannot contain duplicates.

Query the list of CITY names starting with vowels (i.e., a, e, i, o, or u) from STATION. Your result cannot contain duplicates.

Input Format

The STATION table is described as follows:


SOLUTION : 

SELECT DISTINCT CITY

FROM STATION

WHERE CITY LIKE 'A%' 

   OR CITY LIKE 'E%' 

   OR CITY LIKE 'I%' 

   OR CITY LIKE 'O%' 

   OR CITY LIKE 'U%';


EXPLANATION : 

  • DISTINCT: Ensures no duplicate city names are returned.

  • SUBSTR(CITY, 1, 1): Gets the first character of the city name.

  • LOWER(...): Converts the first character to lowercase for a case-insensitive comparison.

  • IN ('a', 'e', 'i', 'o', 'u'): Filters cities that start with a vowel.

When a method in a subclass overrides a method in superclass, it is still possible to call the overridden method using super keyword - Hacker Rank Solution.

When a method in a subclass overrides a method in superclass, it is still possible to call the overridden method using   super   keyword. If you write   super.func()   to call the function   func() , it will call the method that was defined in the superclass. You are given a partially completed code in the editor. Modify the code so that the code prints the following text: Hello I am a motorcycle, I am a cycle with an engine. My ancestor is a cycle who is a vehicle with pedals. SOLUTION : - import java.io.*; import java.util.*; class Cycle {     String define_me() {         return "a vehicle with pedals." ;     } } class Motorcycle extends Cycle {     @Override     String define_me() {         return "a cycle with an engine." ;     }     Motorcycle() {         System.out.println( "Hello I am a motorcycle, I am " + define_me());   ...

Java's System.out.printf function can be used to print formatted output. The purpose of this exercise is to test your understanding of formatting output using printf. To get you started, a portion of the solution is provided for you in the editor; you must format and print the input to complete the solution.

  Input Format Every line of input will contain a  String  followed by an  integer . Each  String  will have a maximum of   alphabetic characters, and each  integer  will be in the inclusive range from   to  . Output Format In each line of output there should be two columns: The first column contains the  String  and is left justified using exactly   characters. The second column contains the  integer , expressed in exactly   digits; if the original input has less than three digits, you must pad your output's leading digits with zeroes. Sample Input java 100 cpp 65 python 50 Sample Output ================================ java 100 cpp 065 python 050 ================================ Solution: import java.util.Scanner; public class Solution {     public static void main(String[] args) {             ...
