题目描述

HackerLand University has the following grading policy:

Every student receives a $\textit{grade}$ in the inclusive range from $0$ to $100$.
Any $\textit{grade}$ less than $\boldsymbol{40}$ is a failing grade.

Sam is a professor at the university and likes to round each student's $\textit{grade}$ according to these rules:

If the difference between the $\textit{grade}$ and the next multiple of $5$ is less than $3$, round $\textit{grade}$ up to the next multiple of $5$.
If the value of $\textit{grade}$ 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 $\textit{grade}$ for each of Sam's $n$ 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, $n$, the number of students.

Each line $\boldsymbol{i}$ of the $n$ subsequent lines contains a single integer, $grades[i]$.

Constraints

$1\leq n\leq60$
$0\leq\textit{grades}[i]\leq100$

Sample Input 0
4
73
67
38
33

Sample Output 0
75
67
40
33

Explanation 0

Student $1$ received a $73$, and the next multiple of $5$ from $73$ is $75$. Since $75-73<3$, the student's grade is rounded to $75$.
Student $2$ received a $67$, and the next multiple of $5$ from $67$ is $70$. Since $70-67=3$, the grade will not be modified and the student's final grade is $67$.
Student $3$ received a $38$, and the next multiple of $5$ from $38$ is $\boldsymbol{40}$. Since $40-38<3$, the student's grade will be rounded to $\boldsymbol{40}$.
Student $4$ received a grade below $33$, so the grade will not be modified and the student's final grade is $33$.
