Terminal python classic sudoku game app.
Sudoku is a number placing puzzle game based on a 9x9 matrix with several given numbers (random numbers generated at the beginning). The object is to place the numbers 1 to 9 in the empty squares (three 3x3 matrix contained in the main 9x9 matrix) so that each row, each column and each square contains the same number only once.
Every play command is composed of three integers: x, y and p.
-> x the number of the row where you want to place your number. Remember to type a number that is between 1 and 9.
-> y the number of the column where you want to place your number. Remember to type a number that is between 1 and 9.
-> p the number you want to place at the intersection of x-y. Remember to type a number that is between 1 and 9.
The application will inform you if your play can't be executed. This occurs, mainly, because of two reasons: it doesn't follow the rules specified above or the numbers you typed are not in the valid range (1-9).
Type x: -1 to stop the execution of the current game.
