KMP算法细节详解（带动图理解）（2）

五、next数组细节理解为什么按照next数组移动就可以保证不跳过匹配成功的字符串呢？前面说过，如果匹配失败子串的首字符的位置会移动到匹配失败的位置，再向左移动next数组[i]格，匹配失败的那一位的next数组记录着前面字符的最大公共前后缀长度，由于前面的前缀都已经于主串匹配过了，只不过后缀后面的位置对不上，那么我们直接将后缀的起始位置对准匹配失败的位置，也就是向左移动next[i]个长度（也....

KMP算法细节详解（带动图理解）（1）

前言KMP算法是为了字符串匹配问题而被研究出来的，字符串匹配问题就是查看一个字符串A是否是字符串B的子串，如果是字串的话，在B的哪个位置？此算法代码简练，但理解起来非常困难，建议挑出一整块时间来专门学习，本文作者写的非常用心，还不了解KMP的小伙伴一定要静下心来慢慢细品，你一定会有所收获一、字符串匹配问题如果遇到这种在一个字符串中寻找另一个字符串的子串这种问题，大多数人第一时间想到的肯定是通过暴....
