一些定义：

#include <bits/stdc++.h>
using namespace std;
using uint = unsigned int;
using ll = long long;
using ull = unsigned long long;
using ld = long double;
using i128 = __int128;
using u128 = unsigned __int128;
using f128 = __float128;

FOR：

#define FOR(i, n, m) for(int i = (n); i <= (m); i ++)
#define ROF(i, n, m) for(int i = (n); i >= (m); i --)
#define REP(i, n) for(int i = 0; i < (n); i ++)

std :: pair：

#define PII pair<int, int>
#define FI(v) v.first
#define SE(v) v.second

container：

#define SZ(v) int(v.size())
template < class T >
using VC = vector<T>;
using VI = VC<int>;
template < class T >
using pq_max = priority_queue<T>;
template < class T >
using pq_min = priority_queue<T, VC<T>, greater<T>>;
#define pb push_back
#define eb emplace_back
#define lb lower_bound
#define ub upper_bound

check max/min ：

template < typename A, typename B >
inline bool chmax(A & x, B y) { return (x < y ? (x = y, true) : false); }
template < typename A, typename B >
inline bool chmin(A & x, B y) { return (x > y ? (x = y, true) : false); }

IO：

#define endl '\n'
#define SHOW(x) #x, '=', x
template < class T >
void rd_s(T & x) { cin >> x; }
void read() {}
template < class H , class ... T >
void read(H & h, T & ... t) { rd_s(h); read(t ...); }
template < class T >
void pt_s(T x) { cout << x; }
void print() { pt_s(endl); }
template < class H , class ... T >
void print(H h, T ... t) { pt_s(h); if(sizeof ... (t)) pt_s(' '); print(t ...); }

定义并输入：

#define INT(...) int __VA_ARGS__; read(__VA_ARGS__)
#define UINT(...) uint __VA_ARGS__; read(__VA_ARGS__)
#define LL(...) ll __VA_ARGS__; read(__VA_ARGS__)
#define ULL(...) ull __VA_ARGS__; read(__VA_ARGS__)
#define STR(...) string __VA_ARGS__; read(__VA_ARGS__)
#define CHAR(...) char __VA_ARGS__; read(__VA_ARGS__)
