基于DC3压缩、BWt压缩、FM_index查询的基因精确查询代码，可以实现对大数据的压缩预处理，再输入查询串，进行精确查询匹配。-Based DC3 compression, BWt compression the query gene precise queries FM_index code can achieve large data compression preprocessing, and then enter a query string, to precisely match

KMP字符串匹配算法，对字符串进行预处理，复杂度为O(m+n)-KMP string matching algorithm, the string preprocessing complexity is O (m+n)
