Blue Jeans [题目链接]Blue Jeans [题目类型]Java暴力 &题意: 就是求k个长度为60的字符串的最长连续公共子串,2<=k<=10 规定: 1. 最长公共串长度小于3不输出 2. 若出现等长的最长的子串,则输出字典序最小的串 &题解: 这个我刚开始用c++写的,真的是恶心到我了,啥都要自己实现,所以突然就想到用Java试试,结果还真的挺简单.思路就是在第1个串中找出所有子串,之后去下面找就行了. String.compareTo(Sting )是字符串…

<题目链接> 题目大意: 就是求k个长度为60的字符串的最长连续公共子串,2<=k<=10 限制条件: 1.  最长公共串长度小于3输出   no significant commonalities 2.  若出现等长的最长的子串,则输出字典序最小的串 解题分析: 将第一个字串的所有子串枚举出来,然后用KMP快速判断该子串是否在所有主串中出现,如果都出现过,那么就按该子串的长度和字典序,不断更新答案,直到得到最终的最优解. #include <cstdio> #incl…

[题目链接] http://poj.org/problem?id=3080 [题目大意] 求k个串的最长公共子串,如果存在多个则输出字典序最小,如果长度小于3则判断查找失败. [题解] 将所有字符串通过拼接符拼成一个串,做一遍后缀数组,二分答案,对于二分所得值,将h数组大于这个值的相邻元素分为一组,判断组内元素是否覆盖全字典,是则答案成立,对于答案扫描sa,输出第一个扫描到的子串即可. [代码] #include <cstdio> #include <cstring> #inclu…

题目链接:http://poj.org/problem?id=3080 该题属于字符串处理中的串模式匹配问题.题目要求我们:给出一个DNA碱基序列,输出最长的相同的碱基子序列.(保证在所有的序列中都有出现) 这里采用了Brute Force算法(由于碱基序列的串长仅为60,规模比较小),这是模式匹配的一种最简单的做法. 设: 最长公共字串为ans,其长度为maxlen. m个碱基序列为p[0]...p[m-1].由于公共子序列是每个碱基序列的子串,因此不妨枚举p[0]的每一个可能的子串s.以s为…
