随笔分类 - 字符串处理——后缀数组
摘要：（7题弟弟。C题知道正解，懒得写了） A：^&^ HDU - 6702 题意：给出A，B。求一个最小的C，使得min=(A^C)&(B^C)最小。 思路：如果存在A和B都有的位，那么全选，就行了，这时结果min为0； 否则，选最小的那个，一个有，一个没有的那一位p，结果min=1<<p； #incl

摘要：KMP，扩展KMP和Manacher就不写了，感觉没多大意思。 之前感觉后缀自动机简直可以解决一切，所以不怎么写后缀数组。 马拉车主要是通过对称中心解决问题，有的时候要通过回文串的边界解决问题，这个时候回文树就用到了，又好写，又强大。 之前整理过一篇后缀自动机的。感觉还要整理一下，顺便把回文树，后缀

摘要：后缀家族已知成员 后缀树 后缀数组 后缀自动机 后缀仙人掌 后缀预言 后缀Splay ？ 后缀树是后缀数组和后缀自动机的祖先? 功能还是比较强大的，在回文串或者字典序方面还是有用处。 而且现在已经有了线性的建树方法。 （但其实我也没用过后缀树。）下面对比后缀自动机和后缀数组 单个字符串问题 不等号是

摘要：Oimaster and sevenk love each other. 题意： 给定一些模板串，询问每个匹配串在多少个模板串里出现过。 思路： 后缀数组办法： 全部模板串连接在一起SA排序，SA数组附件的串里面去验证原串，还没写，我说不清楚，大概是后缀数组+RMQ处理。 后缀自动机办法： 1，广义

摘要：个人感觉： 之前觉得后缀自动机会了，就忽略了后缀数组，现在发现后缀数组+二分的功能很强，而且后缀自动机好像很难实现。 后缀数组可以结合二分，结合树状数组，甚至结合splay等数据结构来处理rmq，lca等问题。。。所以又从头开始搞后缀数组了。 (找不到原博主网站了，失误) 后缀数组解题总结： 单个字
