BM 算法是一个较优的模式匹配算法。一般,如果不考虑模式串的长度,一个具有时间复杂度O(n)的算法应该是最优的了,但是事实不是如此。BM算法可以实现更高效率的模式匹配。分析和实验说明,BM匹配算法对于那些字符集比较大,而模式串中出现的字符比较少的时候,工作效率最快。而且,考虑KMP匹配方式的优化,可以结合KMP匹配和BM匹配,进一步提高效率。
-BM algorithm is a better pattern matching algorithm. General, if we do not consider the length of pattern, a time complexity O (n) algorithm should be optimal, but the fact is not the case. BM algorithm can achieve higher efficiency of pattern matching. Analysis and experiments, BM-matching algorithm for those relatively large character set, and the mode string of characters appearing in less time, the efficiency of the fastest. Moreover, consider the KMP matching optimization, you can match the combination of KMP and BM match, and further improve efficiency.

在用C++写要导出类的库时,我们经常只想暴露接口,而隐藏类的实现细节。也就是说我们提供的头文件里只提供要暴露的公共成员函数的声明,类的其他所有信息都不会在这个头文件里面显示出来。这个时候就要用到接口与实现分离的技术。
-Using C++ to write the database to export category, we just want to expose the regular interface, and the realization of the hidden details of categories. This means that we provide only the first document to be exposed to public member functions of the statement, all other information in this header file will not be displayed inside. This time will be used to achieve separation of interface and technology.
