我草这是什么神仙算法?? 搜题解全是二分图,,,还什么最小权。。。题目里根本没说要求路径和最小啊。。这也不好证明路径和最小时就满足条件啊。。。不太明白正确性。。。 还不如随机冒泡靠谱((((( #include <cstdio> #include <cmath> #include <algorithm> #define pii pair<int,int> using namespace std; typedef double db; const db eps=1e-6; const db pi=acos(-1); int sign(db k){ if (k>eps) return 1; else if (k<-eps) return -1; return 0; } int cmp(db k1,db k2){return sign(k1-k2);} int inmid(db k1,db k2,db k3){return sign(k1-k3)*sign(k2-k3)<=0;}// k3 在 [k1,k2] 内 struct point{ db x,y; point operator + (const point &k1) const{return (point){k1.x+x,k1.y+y};} point operator - (const point &k1) const

How to check if a file is signed in C#? [closed]

♀尐吖头ヾ 提交于 2019-11-26 13:07:50
问题 I\'m writing a program that need to load a few other files. is there a way to check if those files are signed or not, without right clicking them and check? I use 300-400 files that change every few days I need to check DLL/EXE/CAB/OCX/MSI (and maybe also vbs/js) is there a way to check it? 回答1: Assuming you want to check if a file is Authenticode signed and that the certificate is trusted you can pinvoke to WinVerifyTrust in Wintrust.dll . Below is a wrapper (more or less reproduced from

一.题目: 实现一个基本的计算器,输入为包含"(",")","+","-"," "的字符串,输出运算结果. 二.解题思路: 这种题肯定是用栈实现,一般建立两个栈(数字栈和符号栈),有以下几种情况: (1)对于数字,注意连续几位都是数字; (2)对于符号,注意符号的优先级 代码如下: class Solution(object): def calculate(self, s): """ :type s: str :rtype: int """ num_stack = [] sign_stack = [] for i in range(len(s)): if s[i].isdigit(): if num_stack == []: num_stack.append(int(s[i])) elif s[i-1].isdigit(): num_stack[-1] = 10*num_stack[-1]+int(s[i]) else: num_stack.append(int(s[i])) elif s[i] == " ": continue elif (s[i] == "+" or s[i] == "-"): if sign_stack == [] or sign_stack[-1] == "(": sign_stack.append(s[i]) else: a = num_stack.pop

Sign PDF with plain JavaScript

心已入冬 提交于 2019-11-26 12:29:19
With WebCrypto API evolving and being supported by Chrome and Firefox, I would like to use it for digitally signing a PDF document. There is not much of literature around, but I found some examples [1] and a library called PKI.js [2]. In the examples, the signing process is described, but in the end, a signature is returned. I would expect my Base64 PDF file returned again in a signed Base64 string, but sadly, this is not what happens. PKI.js too, to my knowledge, does not provide a way to sign my Base64 PDF. Is there a way to sign a PDF with JavaScript and the WebCrypto API only? The private

Number.sign() in javascript

扶醉桌前 提交于 2019-11-26 11:58:01
问题 Wonder if there are any nontrivial ways of finding number\'s sign (signum function)? May be shorter / faster / more elegant solutions than the obvious one var sign = number > 0 ? 1 : number < 0 ? -1 : 0; Short answer! Use this and you\'ll be safe and fast (source: moz) if (!Math.sign) Math.sign = function(x) { return ((x > 0) - (x < 0)) || +x; }; You may want to look at performance and type-coercing comparison fiddle Long time has passed. Further is mainly for historical reasons. Results For

Signing a Windows EXE file

回眸只為那壹抹淺笑 提交于 2019-11-26 11:57:40
I have an EXE file that I should like to sign so that Windows will not warn the end user about an application from an "unknown publisher". I am not a Windows developer. The application in question is a screensaver generated from an application that generates screensaver applications. As such I have no influence on how the file is generated. I've already found out that I will need a code signing certificate from a CA like Verisign or instantssl.com. What I don't understand is what I need to do (if at all possible) to sign my EXE file. What is a simple explanation? Mel Green's answer took me

Hyperledger Fabric 链码(智能合约)基本操作

China☆狼群 提交于 2019-11-26 10:59:55
目录 链码概念 链码操作 一.链码概念 1.基本概念 Fabric的智能合约称为链码(chaincode),分为系统链码和用户链码。系统链码用来实现系统层面的功能,用户链码实现用户的应用功能。链码被编译成一个独立的应用程序,运行于隔离的Docker容器中。 和以太坊相比,Fabric链码和底层账本是分开的,升级链码时并不需要迁移账本数据到新链码当中,真正实现了逻辑与数据的分离,同时,链码采用Go、Java、Nodejs语言编写。 2.数据流向 Fabric链码通过gprc与peer节点交互 (1)当peer节点收到客户端请求的输入(propsal)后,会通过发送一个链码消息对象(带输入信息,调用者信息)给对应的链码。 (2)链码调用ChaincodeBase里面的invoke方法,通过发送获取数据(getState)和写入数据(putState)消息,向peer节点获取账本状态信息和发送预提交状态。 (3)链码发送最终输出结果给peer节点,节点对输入(propsal)和 输出(propsalreponse)进行背书签名,完成第一段签名提交。 (4)之后客户端收集所有peer节点的第一段提交信息,组装事务(transaction)并签名,发送事务到orderer节点排队,最终orderer产生区块,并发送到各个peer节点,把输入和输出落到账本上,完成第二段提交过程。 3.链码类型
