Solution in PHP (judge verdict: Accepted)

<?php
if (basename(__FILE__) == basename($_SERVER['PHP_SELF'])) {
  while ($line = fgets(STDIN)) {
      list($a, $b, $c) = explode(' ', $line);
      $a = (int)$a;
      $b = (int)$b;
      $c = (int)$c;
      echo $a < $b && $b < $c ? 'Yes' : 'No';
  }
}
?>
