昨天中午弄懂了数组的手工计算方法之后，根据书上例题解出了一道KMP算法的匹配题。我用了next 和nextval两种解决方法，其实就是数组实现的代码片不同。w表示给定的模式字符串next数组代码实现如下：int next[maxw],nextval[maxw],p=0,i,j; next[0]=-1; next[1]=0; for(i

昨天下午在书上看到了KMP算法，看了很多很多很多遍都搞不懂什么逻辑和原理；今天上午又听了学长讲了一遍感觉没大听懂，自己又上网找了很多相关文章，试了很多例子，终于找出来KMP算法中手工计算next、next value数组的方法了。下面我借助网上的相关资料结合用我自己的思路说明一下。一、什么是前缀后缀？ 以字符串s"ababcabc" 为例："a"的前缀和后缀都为空集，共
