Sign on Fence(连续的长为W的一段中最小的数字的最大值)

荒凉一梦 提交于 2019-12-06 01:12:24
题目链接: http://codeforces.com/problemset/problem/484/E 题意:给你个n,n个木板都有高度,宽度都为1 ,给你两个数[l,r]和一个w,求在[l,r]区间的木板里宽度w的最大值,也就是连续的长为W的一段中最小的数字的最大值。 思路:首先想到了二分,找高度,然后就是如果对于每个木板高度,我们把大于等于i木板高度的线段树叶子设为1,其他为0,那么就肯定对于一个高度最长连续的1的值也就是维护一个线段树的和如果大于W 那么就肯定是可行的。所以是个求线段树中最长的连续的1的长度是多少的问题,这个问题要维护线段树的左边连续和,右边连续和,连续和的最大值。对高度从大到小排序,依次分别插入到n颗线段树中形成可持久化线段树(主席树),就能节省许多空间复杂度。维护起来 比较麻烦,好繁琐。。。 #include<cstdio> #include<cstring> #include<queue> #include<cmath> #include<algorithm> #include<map> #include<vector> #include<string> #include<set> #define ll long long using namespace std; const int maxn=1e5+100; int root[maxn],cnt;

apksigner not accepting password

我们两清 提交于 2019-12-06 00:38:13
问题 Up until now I had been signing my apks with the following method: jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore {keystore-file} {apk-file} {keystore-alias} However I am trying to use the new apksigner tool and I cannot get it to work since it always tells me the password is invalid. Which is impossible because I have done it multiple times, with the jarsigner works and with the apksigner doesn't. The commands I have tried are the following: apksigner sign --ks {keystore

Sign a launch4j executable in ant with sign4j and jsign

拈花ヽ惹草 提交于 2019-12-06 00:30:55
I have an application in a Jar and I wrap it in a exe with launch4j so is easy for the user to launch it (in windows). I have a certificate, so I sign the jar (I don't know if this is really necessary because it will be wrapped inside the exe) and I want to sign the exe but it corrupt the executable. I use ant to make all the process and look like: <signjar jar="${jar.location}" alias="${key.alias}" storetype="pkcs12" keystore="${key.file}" storepass="${key.password}" tsaurl="https://timestamp.geotrust.com/tsa" /> <launch4j configFile="launch4j_configuration.xml" fileversion="${version}.0"

Python: Pass inequality as string in dict for evaluation

廉价感情. 提交于 2019-12-06 00:11:43
I need to pass inequalities to a function for evaluation within the function. Is there a way to evaluation the inequality if passed as a string? Or must I pass a representation of the inequality and use if/else statements to generate the sign? senderle Your question is a little vague, but it sounds like you want to evaluate a string containing an expression (such as x > 5 ). Rather than doing that, which is unnecessarily complex, and potentially a security hazard, just define a function, either in the conventional way or using lambda. def gt5(x): return x > 5 or gt5 = lambda x: x > 5 These are

How to reference pound sign (#) in jQuery?

I've been trying a new way to set up a website using jQuery to dynamically get the content when a link is clicked. Here is the jQuery code: $(document).ready(function() { var content_loader = $('#content-loader'); $('#nav ul li a').click(function () { $(this).closest('ul').find('li.active').removeClass('active'); $(this).parent().addClass('active'); content_loader.load('content/' + $(this).attr('data-name') + '.html'); }); content_loader.load('content/home.html'); }); I've been doing it this way since I have a song in the background of my site that I want to play all the time and not start

Python 3爬虫实现有道翻译+GUI并打包成exe文件

大兔子大兔子 提交于 2019-12-05 17:13:31
之前写过爬虫爬取有道翻译实现简单翻译,并且不带GUI页面,而且当时写的时候有道官网还没没有反爬虫机制,时隔几月,有道翻译的网页版有了很大声的变化,所以正好在网易云课堂上找到一个有关破解有道翻译反爬虫机制的课程,顺带加上了使用tkinter时间桌面话,并采用cx_Freeze打包成在没有预装Python环境的windows环境下可以执行的exe文件,其实现在导包成可执行的exe文件,好像py2exe比较常用的,后期我会在好好研究研究, 只是一个非常简单的翻译软件,没有其他功能,只有翻译功能,具体开发流程如下: 写爬虫代码,实现翻译功能, 破解有道翻译的反爬虫机制(这是比较关键的) 使用tkinter写GUI页面 将后台爬虫代码和前台GUI页面结合起来 打包成exe文件(其实是生成了一个安装程序,msi文件,打包的时候顺带将exe文件也生成了) 首先爬取的网页url: http://fanyi.youdao.com/translate_o?smartresult=dict&smartresult=rule 然后再找到发送个给服务器的表单 这表单里面的内容是都需要在代码中发送给服务器的,主要难在表单中的内容,反爬虫的主要就是加密向服务器提交表单的动态值,在这里面,可以很容易的就看出来安歇键值对是动态的,即哪些键对应的值是每次都有变化的,可以看出来,salt和sign对应的值是每次都变的

Python爬取有道翻译

转载自https://blog.csdn.net/nunchakushuang/article/details/75294947 一、正常的爬虫流程: 如果你要爬取他的翻译接口,这个流程还是不能少的。首先我们打开有道翻译的链接: http://fanyi.youdao.com/ 。然后在页面中 右键->检查->Network项 。这时候就来到了网络监听窗口,以后你在这个页面中发送的所有网络请求,都会在 Network 这个地方显示出来。接着我们在翻译的窗口输入我们需要翻译的文字,比如输入 hello 。然后点击 自动翻译 按钮,那么接下来在下面就可以看到浏览器给有道发送的请求,这里截个图看看: 01.png 在上图,我们可以看到发送了很多的网络请求,这里我们点击第一个网络请求进行查看: 02.png 可以看到,我们在点击自动翻译的时候,发送的请求就是上图中 Request URL 的那个 URL ,然后我们再点击那个 Response ,我们可以看到返回的结果: 03.png 并且,现在我们再回到 Headers 的地方,然后滚动到最下面,可以看到有一个 Form Data 的地方,这个下面展示了许多的数据,这些数据就是你在点击 翻译 的时候浏览器给服务器发送的数据: 04.png 对其中几个比较重要的数据进行解释: i :需要进行翻译的字符串,这个地方我们输入的是hello。

What problem or threat does commit signing solve? [closed]

帅比萌擦擦* 提交于 2019-12-05 17:02:51
问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 3 years ago . We use GitHub and we have a request to perform commit signing. After studying the process, it's not clear to me what problem commit signing solves. As I understand the process, there's "local source code" that gets committed to a "local repo" that gets pushed to a "remote repo" .
