考虑霍夫曼每个选择的是最小的两个频率（..

时考虑到在哈夫曼中要每次挑选两个频率最小（即出现次数最小，我那个hNode里的value 是出现的次数），很自然的就想到了std::priority_queue容器，优先队列每次都会弹出队列 中权值最高的元素，这个特性无疑是实现哈夫曼算法的最佳选择。 ... -to consider the Huffman each selected to be the smallest two frequencies (that is, the minimum number, which I hNode"s value is the number of occurrences), it is natural to think of the std : : priority_queue containers, each priority queue queue will pop the top right elements, the Characteristics undoubtedly Huffman algorithm is the best choice. ...
