题目链接:The 18th Zhejiang University Programming Contest Sponsored by TuSimple - G Traffic Light 题解: 题意自己翻译,此题首先肯定是要广搜的,不过要开一个1e5*1e5的数组好像有点困难, 所以用结构体来存每个点的下标,然后从源点开始广搜.定义一个pair<node,int>,第一个存节点信息,第二个存到当前节点的步数,因为还要处理到达每个节点的状态. 状态:走奇数步并且状态为1与走偶数步状态为0的结果…

传送门 题意: 给出了三个新定义: E-prime : ∀ num ∈ E,不存在两个偶数a,b,使得 num=a*b;(简言之,num的一对因子不能全为偶数) E-prime factorization : 定义集合P由 E-prime 元素组成,定义 e = p1*p2*.....*pn:(p1,p2,....,pn ∈ P , |P| = n) E-factorial : 定义 e!! = 2*4*6*8*.........*e:(简言之,偶数e及其之前的偶数连乘积) 输出一个数 e ,求…

题意:模拟栈,正常pop,push,多一个merge A B 形象地说就是就是将栈B堆到栈A上. 题解:直接用list 的pop_back,push_back,splice 模拟, 坑:用splice,第一次超时,正要大改 发现是cin超时... #define _CRT_SECURE_NO_WARNINGS #include<iostream> #include<vector> #include<cstring> #include<set> #includ…

http://acm.zju.edu.cn/onlinejudge/showContestProblem.do?problemId=5738 题意 给你一个map 每个格子里有一个红绿灯,用0,1表示状态.当所在格子为0时只能上下移动,为1时左右移动.人一秒动一次,并且每一秒必须移动,灯每秒改变依次状态.问从起点到终点最短时间. 题解:   就看成一道墙壁会按时间周期改变的走迷宫. 只是墙壁的作用是限制走的方向而不是不能通过. 关于如何判定迷宫无法走通,按套路设了一个vis数组,试了一发就ac了…

题目链接 题意: 题意简单,就是一个简单的数据结构,对栈的模拟操作,可用链表实现,也可以用C++的模板类来实现,但是要注意不能用cin cout,卡时间!!! 代码: #include <stdio.h> #include <iostream> #include <vector> #include <deque> #include <list> #define IO ios::sync_with_stdio(0);\ cin.tie();cout…
