一个合并排序算法。是按照《算法导论》书中的讲解来写的。-A plan to merge sorting algorithm. In accordance with the

shi.c 说明:本程序用于层序遍历二叉树.程序开始时先由用户先根序输入二叉树各结点值,对于空结点输入宏ENDTAG所对的值(暂定为整数0). 建立好二叉树后即可自动进行遍历依次层序输出各结点的值. ----Author:zhg 2006.11.26 E-mail: wudazhg@163.com 仅供参考学习之用，所有权保留-shi.c : The procedures for the binary tree traversal sequence. procedures at the beginning of each user input first-sequence binary tree nodes value, for the importation of empty node by right-ENDTAG value (tentatively scheduled for integer 0). After a good binary tree can be automatically traversal sequence followed output of the node values.---- Author : zhg 2006.11.26 E-mail : wudazhg@163.com for reference purposes only learning, retention of title

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.

该程序能实现的功能，若活动图有回路则无法计算出关键路径，即解决了判断工程的可行性问题。通过对工程活动的输入，可以建立任意的AOE网进行判断。对于输入的网，可以计算出每个活动的最早开始时间，最迟开始时间和全工程可以完成的最早时间，并找出关键路径和关键活动。-the program can achieve the functional, if a circuit map activities can not be calculated critical path, that is a judgment to resolve the feasibility of the project. Right through the importation of construction activities, we can establish arbitrary judgment AOE network. The network for the importation can be calculated for each of the earliest start time, the latest starting time and the entire project will be completed in the first time, and identify key and critical path activities.

数据结构源代码,c数据结构是计算机存储、组织数据的方式。数据结构是指相互之间存在一种或多种特定关系的数据元素的集合。通常情况下，精心选择的数据结构可以带来更高的运行或者存储效率。数据结构往往同高效的检索算法和索引技术有关。
