JAVA：尝试向Huffman树添加虚拟节点

Question

这是我的代码：

   private HuffmanNode buildTree(Map<String, Double> map) {

    Queue<HuffmanNode> newQueue = createNodeQueue(map);
    int checkD = (newQueue.size() - d) / (d - 1);
    double n = d + checkD*(d - checkD);

    while(newQueue.size() > d - 1){

        HuffmanNode[] newArray = new HuffmanNode[d];
        double probCounter = 0;
        for(int i = 0; i < d; i++){
            newArray[i] = newQueue.remove();
            probCounter += newArray[i].probability;
        }

        HuffmanNode newHuffman = new HuffmanNode(null, probCounter, newArray);

        if (n == newQueue.size()){
            newQueue.add(new HuffmanNode("dummy", 0, null));
        }else{
          newQueue.add(newHuffman);  
        }

    }

    return newQueue.remove();

}

我正在尝试编写一个采用整数D> 2的Dary Huffman树程序。目前，我的函数似乎仅在整数为2时才起作用。我试图让我的函数添加一个虚拟对象节点进入队列，它似乎不起作用。
