Are there any mistakes in the special judge of problem 1078E?

I wrote my own special judge to check my answer and it passed, so I think the special judge is wrong.

Or anyone can find mistakes in my code or my special judge?

Thanks a lot. If you can help me, I believe you can find a girlfriend easily. (

upd: My construct method also passed special judges written by my friends. But my friends and I submitted different construct methods, and discoverd that the official special judge might don't support doing operation t many times.

My Code:

#include<bits/stdc++.h>
using namespace std;
#define pb push_back
#define eb emplace_back
#define mp make_pair
#define Fast_IO ios::sync_with_stdio(false);
#define DEBUG fprintf(stderr,"Running on Line %d in Function %s\n",__LINE__,__FUNCTION__)
//mt19937 rnd(chrono::steady_clock::now().time_since_epoch().count());
#define fir first
#define sec second
#define mod 998244353
#define ll long long
#define inf 0x3f3f3f3f
#define INF 0x3f3f3f3f3f3f3f3f
