```cpp
#include <iostream>
using namespace std;
const int MAXN = 5;
int main() {
    int a[MAXN][MAXN];
    for (int i = 0; i < MAXN; i++) {
        for (int j = 0; j < MAXN; j++) {
            cin >> a[i][j];
        }
    }
    int m, n;
    cin >> m >> n;
    swap(m, n);
        swap(m, n);
    }
    for (int i = 0; i < MAXN; i++) {
        swap(a[m - 1][i], a[n - 1][i]);
    }
        for (int j = 0; j < MAXN; j++) {
            cout << a[i][j] << " ";
        }
        cout << endl;
    }

    return 0;
}
