#include <bits/stdc++.h>
using namespace std;

#define int long long

const int N = 1e6 + 7;
const int INF = 0x3f3f3f3f3f3f3f3f;

void solve() {
    int n, x, y, z, a, b;
    cin >> n;
    for (int i = 1;i < n;i += 2) {

            }
            return;
        }
    }
    if (n & 1) {

        else cout << "! 1" << endl;
    }
    else cout << "! 1" << endl;
}

signed main() {
    // ios::sync_with_stdio(false), cin.tie(0);
    int _ = 1;
    cin >> _;
    while (_--) solve();
}

这程序好像有点Bug,我给组数据试试?
