Problem:
A/B Problem

Write a program which reads two integers a and b, and calculates the following values:

a ÷ b: d (in integer)

remainder of a ÷ b: r (in integer)

a ÷ b: f (in real number)

Input

Two integers a and b are given in a line.

Output

Print d, r and f separated by a space in a line. For f, the output should not contain an absolute error greater than 10-5.

Constraints

1 ≤ a, b ≤ 109

Sample Input 1

3 2

Sample Output 1

1 1 1.50000

Solution in PHP (judge verdict: Wrong Answer)

<?php

while ( ! feof(STDIN) ) {
  $row = trim(fgets(STDIN));
  if ($row == '')exit;
  $s = explode(' ', $row);
  echo floor($s[0]/$s[1]).' ';
  echo floor($s[0]%$s[1]).' ';
  echo $s[0]/$s[1];
  echo PHP_EOL;
}
