Здравейте, някой с решение за въпросната задача? Мъча я няколко часа вече.

Моят код:

<?php
$homes = intval(readline());
$presents = intval(readline());
$timesBack = 0;
$additionalPresents = 0;
$homesVisited = 0;
$remainingHomes = $homes;
$totalAddition = 0;
$presentsLeft = $presents;
 for($i = 1; $i <= $homes; $i++) {
    $children = intval(readline());
    $homesVisited++;
    $remainingHomes -= 1;
        if($presentsLeft < $children) {
           $additionalPresents = $children - $presentsLeft;
           $timesBack++;
           $totalAddition += intval(($presents / $homesVisited)) * $remainingHomes + $additionalPresents;
           $presentsLeft = ( $totalAddition - $additionalPresents );
        } else {
    $presentsLeft -= $children;
}


 }
  if($totalAddition <= 0) {
      echo $presentsLeft;
  } else {
      echo $timesBack . PHP_EOL;
      echo $totalAddition;
  }
?>

В judge минавам с 50/100.
