## Day 2: Conditional Statements: If-Else Solution

### Objective

In this challenge, we learn aboutย if-elseย statements. Check out the attached tutorial for more details.

Complete theย getGrade(score)ย function in the editor. It has one parameter: an integer,ย score, denoting the number of points Julia earned on an exam. It must return the letter corresponding to herย gradeย according to the following rules:

• Ifย 25 <ย scoreย <= 30, thenย gradeย = A.
• Ifย 20 <ย scoreย <= 25, thenย gradeย = B.
• Ifย 15 <ย scoreย <= 20, thenย gradeย = C.
• Ifย 10 <ย scoreย <= 15, thenย gradeย = D.
• Ifย 5 <ย scoreย <= 10, thenย gradeย = E.
• Ifย 0 <ย scoreย <= 5, thenย gradeย = F.

### Input Format

Stub code in the editor reads a single integer denotingย scoreย from stdin and passes it to the function.

### Constraints

• 0 <=ย scoreย <= 30

### Output Format

The function must return the value ofย gradeย (i.e., the letter grade) that Julia earned on the exam.

`11`

`D`

### Explanation 0

Becauseย scoreย = 11, it satisfies the conditionย 10 <ย scoreย <= 15ย (which corresponds toย D). Thus, we returnย Dย as our answer.
