题目链接:Nightmare 题意: 给出一张n*m的图,0代表墙,1代表可以走,2代表起始点,3代表终点,4代表炸弹重置点 问是否能从起点到达终点 分析: 一道很好的DFS题目,炸弹重置点必然最多走一次,可能会陷入无限递归,故有一个重要的剪枝,见代码, 此题采用记忆化搜索(不懂の),注意代码的设计思路 #include<cstdio> #include<cstring> #include<algorithm> using namespace std; ][],step…
传送门 题意 给出一张n*m的图 0.墙 1.可走之路 2.起始点 3.终点 4.时间重置点 问是否能到达终点 分析 我的训练专题第一题,一开始我设个vis数组记录,然后写炸,不能处理重置点根vis的关系,然后看了iaccepted这篇blog,换了一种思路,加了一个很好的剪枝,0ms过,足可显示我的搜索思想差.实现差,切记!切记! trick 1.dfs不能保证最先到达终点的为最短距离,不能打标记 2.剪枝说明:如果当前到达该点时间少于该点剩余时间并且步数大于该点步数,则返回 代码 #incl…

非常标准的BFS 第一次写错了很多 1.到达4时设置为墙就好了  避免了死循环 2.不用开d数组   在结构体里面就行了 3.结构体初始化函数的写法: Node(int x=0,int y=0,int oil=0):x(x),y(y),oil(oil){} 4.bfs的FOR里面的判断条件可以写的很清晰!就判断可以的  不可以的直接不处理! #include<bits/stdc++.h> using namespace std; int sx,sy,ex,ey; ][],a[][],d2[][…

今天将介绍一款自动化测试套件名叫nightmare,他是一个基于phantomjs的测试框架,一个基于phantomjs之上为测试应用封装的一套high level API.其API以goto, refresh, click, type…等简单的常用e2e测试动作封装,使得其语义清晰,简洁.其官方在http://www.nightmarejs.org/. 如果你的项目测试不需要想需求和测试人员理解,那么基于nightmare测试或许是一个好的选择,你的降低测试代码的成本,以及测试套件的部署.我们…

一.e2e测试简介 e2e或者端到端(end-to-end)或者UI测试是一种测试方法,它用来测试一个应用从头到尾的流程是否和设计时候所想的一样.简而言之,它从一个用户的角度出发,认为整个系统都是一个黑箱,只有UI会暴露给用户. 想象一下,如果把这些自动化的测试工作换成人工来做,那会多么的令人头疼,尤其是对于那些具有大量交互的应用,手工测试将会以编程不可能的任务. 下文中,将会介绍如何使用Nightmare来进行自动e2e测试. 二.什么是Nightmare? Nightmare是来自Segem…
目标 以腾讯滚动新闻为例,利用nightmare模拟点击下一页,爬取所有页面的信息.首先得感谢node社区godghdai的帮助,开始接触不太熟悉nightmare,感觉很高大上,自己写代码的时候问题也很多,多亏大神的指点. 一.选择模拟的原因 腾讯滚动新闻,是每六十秒更新一次,而且有下一页.要是直接获取页面的话得一页一页的获取,不太方便,又想到了找数据接口,然后通过请求得到数据,结果腾讯新闻的数据接口是加密的,这种想法又泡汤了.因而想到笔记(四)中模拟加载更多的模块,看利用nightmare这…
目标: 解决页面加载更多问题.笔记三中,我们只爬取到网页的部分信息,而点击加载更多后的页面内容是没有提取到的.开始我的想法是找到加载更多的数据接口(可参照:http://www.jianshu.com/p/3fdb6ab47aef),但是我又发现一个问题,当我打开一个订阅号页面时,找到数据接口如下图,点击response会发现里面有相应的内容,对其进行解析时得到的内容却是空的,也就是说我得不到页面的信息.而且我发现有些网页的数据接口是加密的,根本访问不到.因此,我又只能换种思路,看能不能模仿浏览…
