Grading Students
HackerLand University has the following grading policy:
- Every student receives a $grade$ in the inclusive range from $0$ to $100$.
- 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.
