Вот мой код. Даже ускорение cin7tie(0); убрал

include

using namespace std;

int main() { ios_base::sync_with_stdio(false); int t; cin >> t; for (int h = 0; h < t; h++){ int n; cin >> n; if (n > 2){ for (int i = 4; i < 2 * n; i += 2){ cout << '?' << " " << i + 1 << " " << i + 2 << endl; int k; cin >> k; if (k == 1) cout << '!' << " " << i + 1; cout.flush(); } } int a, b, c; cout << '?' << " " << 1 << " " << 2 << endl; cin >> a; cout.flush(); cout << '?' << " " << 1 << " " << 3 << endl; cin >> b; cout.flush(); cout << '?' << " " << 2 << " " << 3 << endl; cin >> c; cout.flush(); if (a == 1 || b == 1) cout << '!' << " " << 1; else if (c == 1) cout << '!' << " " << 2; else cout << '!' << " " << 4; } return 0; } Что не так?
