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

一种基于数据访问流的数据库索引优化方法该方法通过集成业务流程模型与数据模型，抽取了流程活动中包含的数据访问操作和流程的控制结构形成数据访问流，分析了数据访问流中数据访问操作的频度，为频繁数据访问操作所对应的数据项创建索引，达到改善数据访问性能的目的。实验结果表明，该方法提高了数据查询的速度。-A novel method called data-access-flow based index optimization (DAFIO) is proposed to provide automatic index select for databasein order to improve the data access performance. By integrating the data model and process model of the IT systems and getting data access flow, theDAFIO method can analyze the data access flow to find those data item which are accessed frequently, and then create indexes for these frequentitems. The experiment results show that the novel method is effective to improve the data access performance.

一种基本算法！ 现有一个酒店有100个房间，依次编号为1到100，第一个服务员经过，将所有房间门关上；第二个服务员经过将所有编号为2的倍数房门打开；第三个服务员经过将所有编号为3倍数的房门打开的关上，关闭的打开。依此类推；输入一个100以内的正整数N，输出第N服务员经过之后，所有房间的状态。-a basic algorithm! An existing 100 hotel rooms, followed by No. 1-100, after an attendant, all rooms will be closed; Second attendants after all No. 2 in multiples door open; Third attendants after all No. 3 multiples of the open door is shut, Guan the opening closed. XII; The importation of a hundred within the positive integer N, N output after attendants, all rooms in the state.
