#include <bits/stdc++.h>

using namespace std;

using i64 = long long;

    vector<int>a(n);
    for (int i = 0;i < n;i ++){
        cin >> a[i];
    }
    sort(a.begin(),a.end());
    if (n <= 9 || n > 13){
        cout << "No\n";
        return;
    }
    if (a[0] != 1 || a[1] != 1){
        cout << "No\n";
        return;
    }

    for (int i = 1;i < n;i ++){
        if (i != n - 1){
            if (a[i] - a[i - 1] > 2){
                cout << "No\n";

    while (T --){
