Problem Statement

Welcome to Day 12! Check out this video reviewing inheritance

(https://www.youtube.com/watch?v=wlA66hZ4Z74&feature=youtu.be), or just jump right

into the problem.

You are given two classes, Student and Grade, where Student is the base class and

Grade is the derived class. Completed code for Student and stub code for Grade

are provided for you in the editor. Note that Grade inherits all the properties

of Student.

Complete the Grade class by writing a class constructor (Grade(String,String,int,int))

and a char calculate() method. The calculate method should return the character

representative of a Student's *Grade. Score as defined in this chart:

Score Grade

score <= 40 D

40 <= score < 60 B

60 <= score < 75 A

76 <= score < 90 E

90 <= score <= 100 O

Input Format

Input is already handled for you by the code pre-filled in the editor. There are

4 lines of input containing first name, last name, phone, and score, respectively.

Constraints

4<=|first name|,|last name|<=10

phone contains exactly 7 digits

1<=score<=100

Output Format

Output is already handled for you by the code pre-filled in the editor. Your output

will be correct if your Grade class constructor and calculate method are properly written.

Sample Input

Heraldo

Memelli

8135627

90

Sample Output

First Name: Heraldo

Last Name: Memelli

Phone: 8135627

Grade: O
