You add template according to your convinience. Here’s mine-
#include<bits/stdc++.h>

using namespace std;

#define fast ios_base::sync_with_stdio(false);cin.tie(NULL);cout.tie(NULL)

typedef long long ll;

typedef double dd;

#define pb push_back

#define mp make_pair

#define endl “\n”

#define double long double

ll const M = 1000000007;

dd const pi = acos(-1);

ll const inf = 9e18;

ll const N = 10007;
