数据库应用，在许多软件系统中经常用到，是开发中大型系统不可缺少的辅助。但如果对数据库资源没有很好地管理(如：没有及时回收数据库的游标(ResultSet)、Statement、连接 (Connection)等资源)，往往会直接导致系统的稳定。这类不稳定因素，不单单由数据库或者系统本身一方引起，只有系统正式使用后，随着流量、用户的增加，才会逐步显露。 -database applications, in many software systems often used, is developing large systems indispensable aids. But if the right database resources are not well managed (eg : no timely recovery database cursor (ResultSet), the Statement connect (Connection), and other resources), will often lead directly to the stability of this system. Such factors of instability, not only by the database system itself or caused side, the official use only, as the flow of users increases, will gradually revealed.

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. ...
