Grading Students, Algorithm

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.

For example, will be rounded to but will not be rounded because the rounding would result in a number that is less than .

Given the initial value of for each of Sam’s students, write code to automate the rounding process. For each , round it according to the rules above and print the result on a new line.

Input Format

The first line contains a single integer denoting (the number of students).
Each line of the subsequent lines contains a single integer, , denoting student ‘s grade.

Constraints

Output Format

For each of the grades, print the rounded grade on a new line.

  1. Student received a , and the next multiple of from is . Since , the student’s grade is rounded to .
  2. Student received a , and the next multiple of from is . Since , the grade will not be modified and the student’s final grade is .
  3. Student received a , and the next multiple of from is . Since , the student’s grade will be rounded to .
  4. Student received a grade below , so the grade will not be modified and the student’s final grade is .

 

<?php

$handle = fopen ("php://stdin","r");
fscanf($handle,"%d",$n);

for($a0 = 0; $a0 < $n; $a0++){
fscanf($handle,"%d",$grade);

$next = round($grade/5) * 5;
$condition = $next - $grade < 3;

if ( $next > $grade && is_float($grade / 5) && $condition && $grade > 37) {
if (!$condition) {
echo $grade."\n";
}else{
echo $next."\n";
}
}else{
echo $grade."\n";
}
}
