出发日 中午坐大巴前往萧山机场. 哇开心又可以坐飞机了 飞机延误了.在候机大厅里十分无聊,先用机场的电脑玩了会小游戏 然后偷偷切了2个水题 (什么编译器IDE都没有,只能记事本了) 飞机上什么东西都没有,饿着肚子 降落前耳朵十分不适 沈阳好像没有想象中的冷……? 到了宾馆之后先放东西然后去吃烧烤(真是好吃0.0) 晚上回来休息. 热身赛日 早上被冻醒 和Wubaizhe一起吃完KFC回宾馆拿东西,再去报道. 哇这个衣服是黑色的!!看起来好好!! 好评!! 东北大学风景相当不错啊(貌似只要不是我在

5510 Bazinga 题意:给出n个字符串,求满足条件的最大下标值或层数 条件:该字符串之前存在不是 它的子串 的字符串 求解si是不是sj的子串,可以用kmp算法之类的. strstr是黑科技,比手写的kmp快.if(strstr(s[i], s[j]) == NULL),则Si不是Sj的子串. 还有一个重要的剪枝:对于一个串,如果当前找到的串是它的母串,则下一次这个串不用遍历. #include <set> #include <queue> #include <cst

C.Recursive sequence 求ans(x),ans(1)=a,ans(2)=b,ans(n)=ans(n-2)*2+ans(n-1)+n^4 如果直接就去解...很难,毕竟不是那种可以直接化成矩阵的格式,我们也因为这个被卡很长时间 事实上可以把这道式子化成几个基本元素的格式,然后就容易组合了,比如ans(n-2)*2+ans(n-1)+(n-1)^4+4*(n-1)^3+6*(n-1)^2+4*(n-1)^1+1 包含了所有的基本组成形式,化绝对为相对,并且除了一个n-2其他都是n

废话: 这道题很是花了我一番功夫.首先,我不会kmp算法,还专门学了一下这个算法.其次,即使会用kmp,但是如果暴力枚举的话,还是毫无疑问会爆掉.因此在dfs的基础上加上两次剪枝解决了这道题. 题意: 我没有读题,只是队友给我解释了题意,然后我根据题意写的题. 大概意思是给n个字符串,从上到下依次标记为1——n,寻找一个标记最大的串,要求这个串满足:标记比它小的串中至少有一个不是它的子串. 输入: 第一行输入一个整型t,表示共有t组数据. 每组数据首行一个整型n,表示有n个串. 接下来n行,每行

A - Pattern String 留坑. B - Bazinga 题意:找一个最大的i,使得前i - 1个字符串中至少不是它的子串 思路:暴力找,如果有一个串已经符合条件,就不用往上更新 #include <bits/stdc++.h> using namespace std; #define N 510 int t, n; int vis[N]; string s[N]; int main() { ios::sync_with_stdio(false); int t; cin >&
