Compute bloom filter bits for Coursera C3 hm question

C3BMCompute.scala

def compute(nums: Int*) = {
  def h(idx: Int)(num: Int): Int = (((math.pow(num, 2) + math.pow(num, 3)) * idx) % 32).toInt
  val fs: List[Int => Int] = List(h(1), h(2), h(3))
  val result = nums.map { n =>
    val bits = fs.map(_(n)).sorted
    println(s"$n -> ${bits.mkString(",")}")
    (n -> bits)
  }
  println(s"Result: ${result.map(_._2).flatten.sorted.distinct.mkString(",")}")
  result
