The fourth dimension

Printing arrays is a good way to check code output for small arrays like sudoku_game_and_solution, but it becomes unwieldy when dealing with bigger arrays and those with higher dimensions. Another important check is to look at the array's .shape.

Now, you'll create a 4D array that contains two sudoku games and their solutions. numpy is loaded as np. The game_and_solution 3D array you created in the previous example is available, along with new_sudoku_game and new_sudoku_solution.

Create another 3D array called new_game_and_solution with a different 2D game and 2D solution pair: new_sudoku_game and new_sudoku_solution. new_sudoku_game should appear before new_sudoku_solution.
Create a 4D array called games_and_solutions by making an array out of the two 3D arrays: game_and_solution and new_game_and_solution, in that order.
Print the shape of games_and_solutions.
