a ≤ b

Sample Input 1

5 14 80

Sample Output 1

3

Solution in PHP (judge verdict: Accepted)

<?php
$input=trim(fgets(STDIN));
$array_data=explode(" ", $input);
$a=$array_data[0];
$b=$array_data[1];
$c=$array_data[2];
$array_result=array();
for($i=$a;$i<=$b;$i++){
	if($c % $i ==0){
		$array_result[]=$i;
	}
}
printf("%d\n",count($array_result));
