Implementation

  for (int i = level; i > 0; i--) {
    level_list.add(i);
  }

  min_req = level_list.map((j) {
    int num_req = 0;
    for (int i = j; i > 0; i--) {
      num_req += pow(2, i - 1).toInt();
    }
    return filter_len * num_req - 1;
  }).toList();
  min_req = min_req.reversed.toList();
