备忘。

#include<cstdio>
#include<cstring>
#include<algorithm>
#include<bitset>
#include<cassert>
#include<cctype>
#include<cmath>
#include<cstdlib>
#include<ctime>

using namespace std;
typedef long long ll;
typedef long double ld;
#define fi first
#define se second
#define pb push_back
#define mp make_pair
#define pii pair<int,int>

const double PI=acos(-1.0);
const double eps=1e-;
const ll mod=1e9+;
const int inf=0x3f3f3f3f;
const int maxn=1e5+;
const int maxm=+;
#define ios ios::sync_with_stdio(false);cin.tie(0);cout.tie(0);

支持万能头文件的就可以用万能头文件

#include<bits/stdc++.h>
using namespace std;
typedef long long ll;
typedef long double ld;
#define fi first
#define se second
#define pb push_back
#define mp make_pair
#define pii pair<int,int>

const double PI=acos(-1.0);
const double eps=1e-;
const ll mod=1e9+;
const int inf=0x3f3f3f3f;
const int maxn=1e5+;
const int maxm=+;
#define ios ios::sync_with_stdio(false);cin.tie(0);cout.tie(0);
