UNO

很久以前的一个想法，终于实现出来了
忘了封出牌函数导致码就是屎山（
最好是放在 vscode 下运行。

有什么问题一定要说出来啊

For Windows

#include<bits/stdc++.h>
using namespace std;
#ifdef ONLINE_JUDGE
	main(){while(1)new int;}
#endif
#ifndef ONLINE_JUDGE


#include<windows.h>
#include<stdio.h>

#define color(i) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),(i))
#define KEY_DOWN(VK_NONAME) ((GetAsyncKeyState(VK_NONAME)&0x8000)?1:0)

// By: luobotianle
// black base
// This version runs better with vscode

// For Windows
/* 
You can find Linux version at 
https://www.luogu.com.cn/paste/q8ygzglm

Linux version is not so good as Windows
besause I don't know how to change color / pause / read keydown in Linux QAQ
