居然没有我最爱的万能头和宏定义和宏定义和宏定义。。。。。

#include <bits/stdc++.h>
#define int long long
#define pb push_back
#define MOD 1000000007
using namespace std;
const int N = 200005;
void solve() {
    cout<<"ncstacm"<<'\n';
}
signed main() {
    ios::sync_with_stdio(0); cin.tie(0);
    int t=1;
    //cin >> t;
    while (t--) solve();
    return 0;
}
