题目大意:给两个串第一个串是翻译表(密文可以通过翻译表翻译成明文),第二个串是由密文+明文组成,前面是密文(完整的),后面是明文(未必完整),问能不能把第二个串补全,输出最短的一种可能.   分析:题意比较抽象...拿第二个例子来说吧, qwertabcde-> qwert是密文,abcde是明文,密文可以通过上面的qwertyuiopasdfghjklzxcvbnm(26个字母,每个字母变成它所在的下标的字母q->a) 翻译成后面的明文,这么看应该明白怎么回事了吧.然后知到要求出来短的补全,…

题目链接:https://cn.vjudge.net/contest/276379#problem/J 感觉讲的很好的一篇博客:https://subetter.com/articles/extended-kmp-algorithm.html 题目大意:这是一个编译密码的题目,首先给你26个字母分别重新编码后的对应的字母,然后再给你一个字符串,字符串的前一部分是编译过后的,后一部分是编译之前的,但是后一部分可能会有损失,问你用尽量少的字符,将整个字符串补起来,也就是前面是暗文,后面是明文. 具体…

Clairewd’s message 题意:先一个转换表S,表示第i个拉丁字母转换为s[i],即a -> s[1];(a为明文,s[i]为密文).之后给你一串长度为n<= 100000的前面为密文后面为明文的串:让你通过密码转换表S在这个串的后面添加字符,使得前面的密文翻译成明文之后与后面相对应,最后输出添加字符后的串(前面密文照常输出): Sample Input 2 abcdefghijklmnopqrstuvwxyz abcdab qwertyuiopasdfghjklzxcvbnm q…

HDU - 4300 题意:这个题目好难读懂,,先给你一个字母的转换表,然后给你一个字符串密文+明文,密文一定是全的,但明文不一定是全的,求最短的密文和解密后的明文: 题解:由于密文一定是全的,所以他的长度一定大于整个字符串的一半.将这一半先解密,然后和后缀对比一下,求最长的公共前缀.那么就转换为了拓展kmp问题. 1 #include<bits/stdc++.h> 2 using namespace std; 3 4 const int maxn=100010; //字符串长度最大值 5 i…
