PHP Solutions:

$stdin = fopen("php://stdin", "r");fscanf($stdin, "%d\n", $n);
fscanf($stdin, "%[^\n]", $arr_temp);
$num = array_map('intval', preg_split('/ /', $arr_temp, -1, PREG_SPLIT_NO_EMPTY));
$start = 0;
$end = $n-1;
while($start < $end){
    $temp = $num[$start];
    $num[$start] = $num[$end];
    $num[$end] = $temp;
    $start+=1;
    $end-=1;
}
for($i=0;$i<$n;$i++){
    print $num[$i].' ';
}
fclose($stdin);
