基于C++标准模板类库的全文检索算法 -Based on C++ standard template library of full-text search algorithm

快速的序列比对算法，有高效的检索算法在内，对做全文检索的有参考价值。-Fast sequence alignment algorithm, there are efficient retrieval algorithms, including, for to do full-text search of a reference value.

数据结构中PAT树的实现，包括树节点的插入、删除、查找和遍历。PAT tree 在字符串子串匹配上有这非常优异的表现，这使得它经常成为一种高效的全文检索算法，在自然语言处理领域也有广泛的应用。-PAT tree data structure, including the insertion of the tree node, delete, search, and traversal. PAT tree in the string substring match this excellent p
