[HackerRank] Higher Than 75 Marks(left,right사용하기)

Query the Name of any student in STUDENTS who scored higher than 75 Marks. Order your output by the last three characters of each name. If two or more students both have names ending in the same last three characters (i.e.:Bobby, Robby, etc.), secondary sort them by ascending ID.

Input Format

Column	Type
ID	Integer
Name	String
Marks	Integer

The Name column only contains uppercase (A-Z) and lowercase (a-z) letters.

Sample Input

ID	Name	Marks
1	Ashley	81
2	Samantha	75
4	Julia	76
3	Belvet	84

Sample Output
Ashley Julia Belvet

Explanation
Only Ashley, Julia, and Belvet have Marks > 75. If you look at the last three characters of each of their names, there are no duplicates and 'ley' <'lia' < 'vet'.

• query student names ==> SELECT Name

LEFT(NAME, 2) ==> NAME의 왼쪽에서 2개

예) SELECT RIGHT('APPLE', 3) ==> PLE
