#include<fstream>

using namespace std;

int input(istream& in=cin)
{
int x;
in >> x;
return x;
}

int main()
{
int board[9][9]; //creates a 9*9 matrix or a 2d array.

for(int i=0; i<9; i++) //This loops on the rows.
{
for(int j=0; j<9; j++) //This loops on the columns
{
board[i][j] = input(); //you can also connect to the file
//and place the name of your ifstream in the input after opening the file will
//let you read from the file.
}
}

for(int i=0; i<9; i++) //This loops on the rows.
{
for(int j=0; j<9; j++) //This loops on the columns
{
cout << board[i][j] << " ";
}
cout << endl;
