3 月，跳不动了？>>> var add = (function(){ var counter=0; return function(){ return counter++; } })(); add() //实际引用的是add返回的子函数，然后由于子函数有引用，add函数本身无法自由销毁。这样就能实现counter变量的作用域延展。 add() //1 add() //2 来源： oschina 链接： https://my.oschina.net/u/560237/blog/3198342

Count occurrences of unique arrays in array

由 六月ゝ 毕业季﹏ 提交于 2020-02-25 00:47:40
问题 I have a numpy array of various one hot encoded numpy arrays, eg; x = np.array([[1, 0, 0], [0, 0, 1], [1, 0, 0]]) I would like to count the occurances of each unique one hot vector, {[1, 0, 0]: 2, [0, 0, 1]: 1} 回答1: Approach #1 Seems like a perfect setup to use the new functionality of numpy.unique (v1.13 and newer) that lets us work along an axis of a NumPy array - unq_rows, count = np.unique(x,axis=0, return_counts=1) out = {tuple(i):j for i,j in zip(unq_rows,count)} Sample outputs - In

1. (10分) C+±3-1 计算器类 题目描述 下面是一个计算器类的定义，请完成该类成员函数的实现，并编写main()。 class Counter { public: Counter(int num); void increament(); //给原值增1 void decrement(); //给原值减1 int getValue(); //取得计数器值 void print(); //显示计数 private: int value; }; 输入描述 一个整数，用于创建Counter对象 输出描述 调用成员函数进行相关操作后的计算器值 输入样例 5 输出样例 计数器的值为：7 计数器的值为：6 代码： # include <iostream> using namespace std ; class Counter { public : Counter ( int num ) ; void increament ( ) ; //给原值增1 void decrement ( ) ; //给原值减1 int getValue ( ) ; //取得计数器值 void print ( ) ; //显示计数 private : int value ; } ; Counter :: Counter ( int num ) { value = num ; } void Counter ::

C++ compile time counters, revisited

由 房东的猫 提交于 2020-02-12 08:05:44
问题 TL;DR Before you attempt to read this whole post, know that: a solution to the presented issue has been found by myself, but I'm still eager to know if the analysis is correct; I've packaged the solution into a fameta::counter class that solves a few remaining quirks. You can find it on github; you can see it at work on godbolt. How it all started Since Filip Roséen discovered/invented, in 2015, the black magic that compile time counters are in C++, I have been mildly obsessed with the device

委托编程指南

由 ⅰ亾dé卋堺 提交于 2020-02-01 10:57:40
一.什么是委托 委托的本质是一种数据类型,和类类型一样，只是一种数据类型没什么神秘的地方，委托是一种引用数据类型， 表示对具有特定参数列表和返回类型的方法的引用 。在实例化委托时，你可以将其实例与任何兼容的方法(参数和返回值，简称方法的签名)相关联,再通俗一点的讲， 委托是可以将"方法"定义成变量的数据类型 。 二.为什么使用委托 委托用于将方法作为参数传递给其他方法，当某个方法直接调用有困难时，我们就想找一个"中间人"来帮我们调用，这个中间人就是委托。 委托的简单应用的第一个例子：从窗体向主窗体传递值，实现主窗体窗体刷新 主窗体： public partial class FrmMain : Form { public FrmMain() { InitializeComponent(); FrmOther objFrm = new FrmOther(); //将从窗体的委托变量和主窗体的对应方法关联 objFrm.msgSender = this.Receiver; objFrm.Show(); } /// <summary> /// 接收委托传递的信息 /// </summary> /// <param name="counter"></param> private void Receiver(string counter) { this.lblCount.Text =
