分析：

就是一个输入字符串

然后没四位输出一个答案就行了

代码

#include "bits/stdc++.h"

using namespace std;
#define int long long
#define endl "\n"
#define PII pair<int,int>
#define PIII pair<int,PII>
const int MOD = 1e9 + 7;
const int N = 3e5;

void slu() {
    int n;
    cin >> n;
    n = pow(2, n);
    string t;
    for (int i = 0; i < n; i++) {
        for (int j = 0; j < n; j++) {
            char temp;
            cin >> temp;
            t.push_back(temp);
        }
    }
    int res = 0;
    for (int i = 0, j = 3; i < t.size(); i++, j--) {
        if (t[i] == '#')res += pow(2, j);
        if (j == 0) {
            j = 4;
            cout << res << " ";
            res = 0;
        }
    }
}

signed main() {
    ios_base::sync_with_stdio(0);
    cin.tie(0);
    cout.tie(0);
    int T;
//    cin >> T;
    T = 1;
    while (T--)slu();

}
