Description 有两个字符串,每次用一个中取出下一位,放在一个字符串中,如果当前字符串的后缀是另一个字符串就删除. Sol KMP+栈. 用一个栈来维护新加的字符串就可以了.. 一开始我非常的naive,写了个链表,只能过5个点,因为起始位置不太好搞... Code /************************************************************** Problem: 3942 User: BeiYu Language: C++ Result:…

题目链接:BZOJ - 3942 题目分析 我们发现,删掉一段 T 之后,被删除的部分前面的一段可能和后面的一段连接起来出现新的 T . 所以我们删掉一段 T 之后应该接着被删除的位置之前的继续向后匹配. 那么我们维护一个栈,一直向后匹配,如果栈顶出现了 T ,就弹出 T 个字符,然后继续从新的栈顶向后匹配就可以了. 匹配使用 KMP 算法. 代码 #include <iostream> #include <cstdio> #include <cstring> #inc…

好久没写kmp都不会写了-- 开两个栈,s存当前串,c存匹配位置 用t串在栈s上匹配,栈每次入栈一个原串字符,用t串匹配一下,如果栈s末尾匹配了t则弹栈 #include<iostream> #include<cstdio> #include<cstring> using namespace std; const int N=1000005; int n,m,c[N],top,ne[N]; char a[N],b[N],s[N]; void gtnxt() { ne[0…

AC自动机.为什么洛谷水题赛会出现这种题然而并不会那么题意就不说啦 .终于会写AC自动机判断是否是子串啦...用到kmp的就可以用AC自动机水过去啦 #include<cstdio> #include<cstring> #include<iostream> #include<algorithm> #include<queue> using namespace std; #define rep(i,s,t) for(int i=s;i<=t;…
