The following console program uses parameters and returns to produce three lines of output. What are they? 

function bludger($y) {
    $x = intval($y / 1000);
    $z = ($x + $y);
    $x = quaffle($z, $y);
    print("bludger: x = $x, y = $y, z = $z\n");
}

function quaffle($x, $y) {
    $z = snitch($x + $y, $y);
    $y = intval($y / $z);
    print("quaffle: x = $x, y = $y, z = $z\n");
    return $z;
}

function snitch($x, $y) {
    $y = $x / ($x % 10);
    print("snitch: x = $x, y = $y\n");
    return $y;
}

bludger(2001);
