int main() {
  using Matrix = std::array<std::array<int, 3>, 3>; 
  Matrix m;
  // read
  for (size_t row = 0; row < 3; row++) {
    for (size_t col = 0; col < 3; col++) {
      std::cin >> m[row][col];
    }
  }
  // display
  for (auto const& r: m) {
    for (auto c: r) {
      std::cout << c << ' ';
