/*
* Complete the 'gradingStudents' function below.
* The function is expected to return an INTEGER_ARRAY.
* The function accepts INTEGER_ARRAY grades as parameter.
*
* *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 38)
*do not round (60 - 57 is 3 or higher)
