# Grading Students

HackerLand University has the following grading policy:

- Every student receives a in the inclusive range from to .
- Any less than is a failing grade.

Sam is a professor at the university and likes to round each student's according to these rules:

- If the difference between the and the next multiple of is less than , round up to the next multiple of .
- If the value of is less than , no rounding occurs as the result will still be a failing grade.

**Examples**

- round to (85 - 84 is less than 3)
- do not round (result is less than 40)
- do not round (60 - 57 is 3 or higher)

Given the initial value of for each of Sam's students, write code to automate the rounding process.

**Function Description**

Complete the function *gradingStudents* in the editor below.

gradingStudents has the following parameter(s):

*int grades[n]*: the grades before rounding

**Returns**

*int[n]*: the grades after rounding as appropriate

**Input Format**

The first line contains a single integer, , the number of students.

Each line of the subsequent lines contains a single integer, .

**Constraints**

**Sample Input 0**

```
4
73
67

```

**Explanation 0**

- Student received a , and the next multiple of from is . Since , the student's grade is rounded to .
- Student received a , and the next multiple of from is . Since , the grade will not be modified and the student's final grade is .
- Student received a , and the next multiple of from is . Since , the student's grade will be rounded to .
- Student received a grade below , so the grade will not be modified and the student's final grade is .
