/C++万能头/：#include<bits/stdc++.h>

C++快读

#include<bits/stdc++.h>
#define ll long long

using namespace std;

inline int read() {
	int x = 0, f = 1;
	char c = getchar();
	while (c < '0' || c > '9') {
		if (c == '-') f = -1;
		c = getchar();
	}

freopen("test.txt","w",stdout)——将控制台控制（输出）改为文件控制（输出），用于oj上某些题要求，且此代码必须写于int main(){}大括号之中`

freopen("A.in","r",stdin)（输入） freopen("A.out","w",stdout)（输出）,规则如上

0~n个一的求法：(1<<n)-1

从小到大数组排序：

一. sort——sort（列表名称,列表名称+列表元素数量）

二. bool——bool cmp（int x,int y） { //return x<y; 从小到大排序 //return x>y; 从大到小排序 }

三.

1、栈列的定义 stack<关键词> 栈名;

2、栈列的基本操作栈名.操作函数名() 栈名.push(入栈元素) //入栈栈名.pop() //出栈栈名.stack() //返回值为栈头栈名.size() //返回值为栈中元素个数栈名.empty() //栈空返回 true 不空返回false 栈名.empty() //栈空返回 true 不空返回false

要执行出栈和查看栈顶操作时--栈必须非空

//基础栈代码
#include<bits/stdc++.h>
using namespace std;
int main()
{
//创建一个栈
//	stack<类型> 栈名1;
stack stk;
stk.push(1);
stk.push(3);
stk.push(2);
stk.pop();//这个不能输出
cout << "栈顶" << stk.top() << endl;
cout << "栈中元素个数" << stk.size() << endl;
cout << "栈是否为空，空是true,不空是false" << stk.empty() << endl;
//连续输入多个元素
int n;
cin >> n;
for(int i=1;i<=n;i++)
{
int x;
cin >>x;
stk.push(x);
}
//遍历栈中元素
while( !stk.empty() )
{
cout << stk.top() << " ";
stk.pop();
}
return 0;
}

queue<关键词> 队名;
2、队列的基本操作
队名.操作函数名()
队名.push(入栈元素) //入队
队名.pop()          //出队
队名.front()          //返回值为队头
队名.back()         //返回队尾
队名.size()         //返回值为队中元素个数
队名.empty()        //栈空返回 true 不空返回false
!队名.empty()        //栈空返回 true 不空返回false

**min(a,b);//返回a,b的较小值
max(a,b);//返回a,b的较大值
abs(x);//返回x的绝对值
pow(a,b);//返回a的b次方
sqrt(a);//返回更号a**

按位与& (同1则1，一0则0)

例如

3&5
   0011
&  0101
-----------
   0001
3&5 = 1

Copy

按位或| (同0则0，一1则1)

例如

3|5
   0011
|  0101
-----------
   0111
3|5 = 7

Copy

按位取反~ (01互换)

例如1

~3（8位二进制数）
~   0000 0011
----------------
    1111 1100
~3=-4

Copy

按位异或^ (不同为1，相同为0)

例如

3^5
   0011
^  0101
-----------
   0110
3^5 = 6

Copy

位运算符

左移运算：`<<`

用法： x<<y

作用：将表示 x 的二进制数的每一位左移 y 位，移出去的数就丢掉，空余地方用 0 补位。

例如：一个二进制数 10101011 将其左移 3 位，得到 01011000。

右移运算：`>>`

用法： x>>y

作用：将表示 x 的二进制数的每一位右移 y 位，移出去的数就丢掉，空余地方用 0 补位。

例如：一个二进制数 10101011 将其右移 3 位，得到 00010101。

按位与运算： `&`

用法：x&y

作用：按位进行与运算。

例如：1101 和 0011 进行与运算就为：0001。

按位或运算： `|`

用法：x|y

作用：按位进行或运算。

例如：1101 和 0011 进行或运算就为：1111。

按位异或运算： `^`

用法：x^y

作用：按位进行异或运算。

例如：1101 和 0011 进行异或运算就为：0001。

按位非运算： `~`

用法：~x

作用：按位进行非运算。

例如：1101进行非运算就为：0010。

状态压缩常用位运算符技巧

1.取出x的第k位:

y = x&(1<<(k-1));//i<<(k-1)能够做成一个第k为1，其余位为0，如:10000 的二进制数，再结合位与运算就能提取到变量x的二进制中第k位数为1还是0了，常用于判断

Copy

2.将x第k位取反:

x ^= (1<<(k-1));//通过左移制作一个10000般的二进制数，然后结合异或运算的特点，将变量x的二进制中第k位数取反

Copy

3.将x第k位变为1：

x |= (1<<(k-1));//通过左移制作一个10000般的二进制数，然后结合异或运算的特点，将变量x的二进制中第k位数修改为1

Copy

4.将x第k位变为0：

x &= (~(1<<(k-1))); //通过左移制作一个0001 0000般的二进制数，然后位非运算将其修改为1110 0000般的二进制数，最后结合位与运算的特点，将变量x的二进制中第k位数修改为0

Copy

5.将x最靠右的1去掉：

x = x&(x-1); //减去1会将数字二进制中末尾的1去掉，然后需要借位的地方全变为1，如原1010 0000，减去1后变成1001 1111，再进位与运算得1000 0000，相当于去掉末尾1

Copy

6.取出x最靠右的1:

y = x&(-x); //结合负数的二进制的特点，如数字20的二进制为0001 0100，-20的二进制为1110 1100，再进行位与运算能够获取到二进制数100也就是4，及提前数字x中包含的最大2的指数值

Copy

7.判断是否有两个连续的一：

if(x&(x<<1)) cout<<"YES"; //左移后的数字会进行偏移，如13的二进制0000 1101，左移后未0001 1010，再进行位与运算，连续的1会在偏移后有至少一个1重叠，让结果不为0，如果结果为0，说明不存在连续的1;

memset(数组名，0，sizeof 数组名);//只能置为0或者-1

C++二分查找（示例代码）

#include<bits/stdc++.h>
using namespace std;
int arr[200005];
int main(){
	int n,m;
	cin>>n>>m;
	for(int i=1;i<=n;i++){
		cin>>arr[i];
	}
	sort(arr,arr+1+n);
	for(int i=1;i<=m;i++){
		int t;
		cin>>t;
		int ans;
		int left=1,right=n;
		while(left<=right){
			int mid = (left+right)/2;
			if(arr[mid]>=t){
				ans = mid;
				right = mid-1;
			}
			if(arr[mid]<t) left = mid+1;
		}
		if(arr[ans]==t) cout<<"有这个数";
		else cout<<"没有这个数"; 
	}
	return 0;
}

递归排序（利用树生成，树，图论等）

//n个球摸m次可放回
#include<iostream>
#include<cstdio>
using namespace std;
int q[105];//q[x] = y 表示第x次摸到的是y号球 
int n,m;//n个球摸m次 
void dfs(int k)//表示第k次摸球    n个球摸m次 
{
	if(k>m)//摸第m+1次结束 
	{
		for(int i=1;i<=m;i++)cout << q[i] << " ";
		cout << endl;
		return ;
	}
	for(int i=1;i<=n;i++)//一共有1~n个球 
	{
		q[k] = i;//第k次摸了i号球 
		dfs(k+1);//第k+1次摸球 
	} 
} 
int main()
{
	cin >> n >> m;
	dfs(1);
	return 0;
}

//n个球摸m次不放回
#include<iostream>
#include<cstdio>
using namespace std;
int q[105];
int vis[105];//vis[1]=1
int n,m;
void dfs(int k)//表示第k次摸球    n个球摸m次 
{
	if(k>m)
	{
		for(int i=1;i<=m;i++)cout << q[i] << " ";
		cout << endl;
		return ;
	}
	for(int i=1;i<=n;i++)
	{
		if( vis[i] ) continue;
		q[k] = i;
		vis[i] = 1;
		dfs(k+1); 
		vis[i] = 0;//回溯 
	} 
} 
int main()
{
	cin >> n >> m;
	dfs(1);
	return 0;
}

//n个球摸m个的情况
#include<iostream>
#include<cstdio>
using namespace std;
int q[105];
int vis[105];//vis[1]=1
int n,m;
void dfs(int k,int pre)//表示第k次摸球    n个球摸m次 
{
	if(k>m)
	{
		for(int i=1;i<=m;i++)cout << q[i] << " ";
