Given an array of integers, calculate the ratios of its elements that are positive, negative, and zero. Print the decimal value of each fraction on a new line with places after the decimal.

// Complete the plusMinus function below.
function plusMinus($arr) {

        $pos=0;
        $neg=0;
        $zero=0;
    for($i=0;$i<count($arr);$i++)
    {
        if($arr[$i]>0)
        {
            $pos++;
        }
        else if($arr[$i]< 0)
        {
            $neg++;
        }
        else
        {
            $zero++;
        }
    }
   $pos= $pos/count($arr);
 $neg= $neg/count($arr);
 $zero= $zero/count($arr);
$res= array($pos,$neg,$zero);
    echo $res[0]."\n".$res[1]."\n".$res[2];

}

$stdin = fopen("php://stdin", "r");

fscanf($stdin, "%d\n", $n);

fscanf($stdin, "%[^\n]", $arr_temp);

$arr = array_map('intval', preg_split('/ /', $arr_temp, -1, PREG_SPLIT_NO_EMPTY));

plusMinus($arr);

fclose($stdin);
