题目链接 Description 给出\(n\)个序列.找出这\(n\)个序列的最长相同子串. 在这里,相同定义为:两个子串长度相同且一个串的全部元素加上一个数就会变成另一个串. 思路 参考:hzwer. 法一:kmp 在第一个串中枚举答案串的开头位置,与其余\(n-1\)个串做\(kmp\). 法二:后缀数组 将\(n\)个串拼接起来.二分答案\(len\),将\(height\)分组,\(check\)是否有一组个数\(\geq len\)且落在\(n\)个不同的串中. 注意:\(n\)个串…

要求:求两个字符串的最长公共子串,如“abcdefg”和“adefgwgeweg”的最长公共子串为“defg”(子串必须是连续的) public class Main03{ // 求解两个字符号的最长公共子串 public static String maxSubstring(String strOne, String strTwo){ // 参数检查 if(strOne==null || strTwo == null){ return null; } if(strOne.equals("&qu…
还是直接上转移方程: 动规只能解决O(n^2)的最长公共子串问题 使用后缀数组或者SAM可以高效地解决这个问题 所以,对于这个问题,动规的代码就不给出了 直接给出SAM的实现,也为以后学习SAM打下一个基础 具体做法是,对一个串建后缀自动机,把另一个串在自动机上跑,维护一下最大的匹配的长度就好了 #include<cstdio> #include<cstring> #include<algorithm> using namespace std; int n,ans; ]…
