<?php

fscanf(STDIN, "%d\n", &$n);
$a = array_fill(0, $n+1, 0);

for ($i = 0; $i < $n; ++$i) {
fscanf(STDIN, "%d\n", &$v);
++$a[$v];
}

//sort($a, SORT_NUMERIC);

for ($i = 0; $i < $n+1; ++$i) {
echo ".";
for ($j = 0; $j < $a[$i]; ++$j) {
echo $i."\n";
}
}
?>

The second loop goes down from 1 milion to how many number you want to
