NOI Linux Sublime Text 使用指南

感觉 noi linux 的vscode还是太鸡肋，所以用了用subline，莫名好用
下面是食用指难。

首先打开，不好看，我们可以点击这里更改相应主题
然后我们要点 file 打开文件夹

打开/关闭侧边栏的快捷键是 Ctrl+K+B (K和B同时按)
然后sublime不能输入，直接用文件输入输出。
所以这样的分屏比较优

打开Preferences中的Key Bindings，将左边内容粘贴到右边，然后搜索alt+shift+5，改成如下内容

"keys": ["alt+shift+5"],
"command": "set_layout",
"args":
{
	"cols": [0.0, 0.5, 1.0],
	"rows": [0.0, 0.5, 1.0],
	"cells":
	[
		[0, 0, 1, 2], [1, 0, 2, 1],
		[1, 1, 2, 2]
	]
}

然后快捷键alt+shift+5就可以分屏了。
接下来是C++的编译，我们打开Tools中的Build System中的New Build System

将以下代码放进去后保存命名（我的是MyC++）

{
    "encoding": "utf-8",
    "working_dir": "$file_path",
    "variants": 
    [
        {   
        "name": "Run",
        "shell_cmd": "g++ -o \"$file_base_name\" \"$file\" -std=c++14 -O2 -Wall && ./\"$file_base_name\" "
        }
    ]
}

然后在刚刚的Tools中的Build System选择就可以了。编译加运行按ctrl+B

缺省源打开tools的developer中的new snippet

<snippet>
  <content><![CDATA[
你的码头
]]></content>
  <tabTrigger>#i</tabTrigger>
  <scope>source.c++</scope>
</snippet>

自留

<snippet>
	<content><![CDATA[
#include<bits/stdc++.h>

#define se second

std::mt19937 myrand(std::chrono::high_resolution_clock::now().time_since_epoch().count());
inline int R(int n){return myrand()%n+1;}
inline int read(){char ch=getchar();int x=0,f=1;for(;ch<'0'||ch>'9';ch=getchar())if(ch=='-')f=-1;for(;ch>='0'&&ch<='9';ch=getchar())x=(x<<3)+(x<<1)+(ch^48);return x*f;}
const int N=2e5+10,inf=1e9;
inline void Min(int &x,int y){if(x>y)x=y;}
inline void Max(int &x,int y){if(x<y)x=y;}
 
signed main(){
    freopen("in.in","r",stdin);freopen("out.out","w",stdout);
    std::ios::sync_with_stdio(false);std::cin.tie(0);std::cout.tie(0);
    $2
}]]></content>
	<!-- Optional: Set a tabTrigger to define how to trigger the snippet -->

	// Place your snippets for cpp here. Each snippet is defined under a snippet name and has a prefix, body and 
	// description. The prefix is what is used to trigger the snippet and the body will be expanded and inserted. Possible variables are:
	// $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders. Placeholders with the 
	// same ids are connected.
	// Example:
	"Print to console": {
		"prefix": "#i",
		"body": [
			"#include<bits/stdc++.h>",
			"#define eb emplace_back",
			"#define fo(i,s,t) for(int i=s;i<=t;++i)",

			"typedef unsigned long long ull;",

A

都是线性变换，大胆猜，首先三个点可以直接计算，然后枚举一个点，剩下两个点有多种可能性，注意到在单位圆上，只要两个点的中点确定，两个点就确定了，半径为 \(R\)，中点向顶点方向移动 \(\frac{R}{2}\) 就是新圆心。

B

暴力了，对于 \(n\le 20\)，
