哈夫曼树和哈夫曼编码： 从终端输入若干个字符及其对应的整数，将整数作为结点的权值，建立哈夫曼树，然后对各字符进行哈夫曼编码。最后打印哈夫曼树和对应的哈夫曼编码。 设计要求： ⑴ 哈夫曼殊和哈夫曼编码的存储表示参考教材事例 ⑵ 在程序中构造四个子程序为 ① int createhtree(HTree *t) /*根据输入的字符及其权值建立哈夫曼树*/ ② void coding(HTree *t, char *code) /*对哈夫曼树进行编码*/ ③ void printhtree(HTree *t, int* path) /*中序打印树*/ ④ void printcode(HTree *t) /*输出个字符的哈夫曼编码*/ -Huffman tree and the Huffman coding: input from the terminal a number of characters and their corresponding integer, will be an integer as node weights, the establishment of Huffman tree, and then on the characters Huffman. Finally print Huffman tree and the corresponding Huffman. Design requirements: ⑴ Huffman and Huffman coding is that the reference materials storage ⑵ examples constructed in the procedure for the four subroutines ① int createhtree (HTree* t)/* input characters in accordance with its right value the establishment of Huffman tree*/② void coding (HTree* t, char* code)/* Huffman tree to encode*/③ void printhtree (HTree* t, int* path)/* Pri

―图数据类型的实现――问题描述：图是一种较线性表和树更为复杂的数据结构。在图形结构中，结点之间的关系是任意的，任意两个数据元素之间都可能相关，因此，图的应用非常广泛，已渗入到诸如语言学‘逻辑学、物理、化学、电讯工程、计算机科学及数学的其它分支中。因此，实现图这种数据类型也尤为重要，在该练习中即要实现图的抽象数据类型。基本要求：2、 定义出图的ADT；3、 采用邻接矩阵及邻接表的存储结构（有向图也可使用十字链表）实现以下操作：a. 构造图 b. 销毁图 c. 定位操作d. 访问图中某个顶点的操作e. 给图中某个顶点赋值的操作f. 找图中某个顶点的第一个邻接点g. 找出图G中顶点v相对于w的下一个邻接点h. 在图G中添加新顶点vi. 删除图G中顶点vj. 在图G中插入一条边k. 在图G中删除一条边l. 实现图的深度遍历操作m. 实现图的广度遍历操作参考提示：具体内容参看教科书本156页实验要求：对于以上具体操作要求实现时有良好的用户交互界面。详细设计、编码、测试。-2 ADT3 a. b. c. d. e. f. g.

经典的数据结构算法-classical algorithm data structure

Many applications use connection/object pool. A program may require a IMAP connection pool and LDAP connection pool. One could easily implement a IMAP connection pool, then take the existing code and implement a LDAP connection pool. The program grows, and now there is a need for a pool of threads. So just take the IMAP connection pool and convert that to a pool of threads (Copy, paste, find, replace????). Need to make some changes to the pool implementation? Not a very easy task, since the code has been duplicated in many places. Re-inventing source code is not an intelligent approach in an object oriented environment which encourages re-usability. It seems to make more sense to implement a pool that can contain any arbitrary type rather than duplicating code. How does one do that? The answer is to use type parameterization, more commonly referred to as templates.-connection/object pool. A program may require a IMAP connection po ol and LDAP connection pool.
