传送门求一个串的最长回文子串的长度 1.后缀数组把这个串反转后接到原串的后面,中间连一个没有出现过的字符. 然后求这个新字符串的某两个后缀的公共前缀的最大值即可. ——代码 #include <cstdio> #include <cstring> #include <iostream> #define N 2000010 #define max(x, y) ((x) > (y) ? (x) : (y)) int n, m, len, ans; int buc[…

HDU - 3948 后缀数组+Manacher

题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=3948 题意:给定一个字符串,求字符串本质不同的回文子串个数. 思路:主要参考该篇解题报告先按照manacher的构造方法改造一遍串,然后跑一遍manacher.求出以i为中心的最长回文串长度p[i]. 然后跑一遍后缀数组,若已经求得后缀sa[i-1]对答案的贡献,然后现在计算后缀sa[i],本来是要加上以sa[i]为中心的回文串的个数p[sa[i]]. 我们可以维护一个tmp,也就是上图中蓝色的框…
