+         * Any grade less than 40 is a failing grade.
+         * 
+         * Sam is a professor at the university and likes to round each student's grade according to these rules:
+         * If the difference between the grade and the next multiple of 5 is less than 3, round grade up to the next multiple of 5.
+         * If the value of grade is less than 38, no rounding occurs as the result will still be a failing grade.
+         * 
+         * Examples
+         * grade = 84 round to 85 (85 - 84 is less than 3)
+         * grade = 29 do not round (result is less than 40)
+         * grade = 57 do not round (60 - 57 is 3 or higher)
+         * Given the initial value of grade for each of Sam's n students, write code to automate the rounding process.
