一个关于KMP的算法，没有错误。但是会在计算NEXT函数以后出现原来的模式串改变的情况，求大神

即使把原来的模式串copy到另一个数组中，经过NEXT函数求值以后还是会变。

字符串模式匹配之KMP算法图解与 next 数组原理和实现方案

之前说到，朴素的匹配，每趟比较，都要回溯主串的指针，费事。则 KMP 就是对朴素匹配的一种改进。正好复习一下。 KMP 算法其改进思想在于：每当一趟匹配过程中出现字符比较不相等时，不需要回溯主串的 i指针，而是利用已经得到的“部分匹配”的结果将模式子串向右“滑动”尽可能远的一段距离后...

KMP算法 --- 深入理解next数组

在KMP算法中有个数组，叫做前缀数组，也有的叫next数组。每一个子串有一个固定的next数组，它记录着字符串匹配过程中失配情况下可以向前多跳几个字符。当然它描述的也是子串的对称程度，程度越高，值越大，当然之前可能出现再匹配的机会就更大。这个next数组的求法是KMP算法的关键，...

KMP算法Next数组计算

KMP算法是在最近这两年的软件设计师考试中才出现的。2次都是让求Next函数的序列（其实是）。先看看题吧。（2011年下半年上午题）（2012年上半年上午题）其实做这个题很简单，我先说说这个题里的各种概念。给定的字符串叫做模式串T。j表示next函数的参数，其值是从1到n。而k则表示一种情况...
