[POJ1509]Glass Beads [题目描述]给定字符串S,并规定首尾相连成环,求出最小字典序. [输入]输入有多个数据,第一行只包括正整数N,表示有N组数据.每个数据包括一行,输入该字符串. [输出]对于每个数据,输出一行数据表示从哪一个字母开始为最小字典序排列. [题解思路]暴力是个好东西,咳咳咳 该题为赤果果的最小表示. Q:最小表示是什么? A:看题目描述撒. Q:怎么个表示法呢? A:莫急,往下看哈. 还是从暴力开始讲:依次比较n个以不同位置字符开头的字符串,找到其中字典序最小…

Description 求字符串的最小循环表示. Sol SAM. 把原串复制一遍,建出SAM,然后每次选最小的一个跑 \(len\) 次,这就是最小循环表示的最后一个节点,然后 \(x-len+1\) 即为答案. Code #include<cstdio> #include<cstring> #include<iostream> using namespace std; const int N = 20005; int n,rt,lst,cnt,l; int s[N]…

题意:求一个字符串的最小表示的开始下标 就当模板题写了 把字符串重复一遍,再建后缀自动机,贪心的选最小字典序在上面走len步 因为走出来的一定是子串,长度又是len,所以一定是原来的字符串旋转得到的,就解决了 const maxn=; type node=record go:..]of longint; step,fa:longint; end; var sam:..maxn]of node; s,ans:ansistring; len,tot,last,t:longint; procedure…

[题目描述] 给定长度为n(n<=300000)的循环同构的字符串,定义最小表示为该字符串的字典序最小的同构表示,请输出这个表示. [输入格式] 第一行是串的长度,第二行是字符串. [输出格式] 串的最小表示. [样例输入] 10 helloworld [样例输出] dhelloworl [题目来源] HZOI2015 改编自poj1509 算法很显然,需要注意的是:s[len+1]要赋值成一个较大值. #include <iostream> #include <cstring&g…
