Write a Python program that will ask the user for two integers a and b such that 0 < a < b. Next, the user will be prompted to enter divisors (one or more). All divisors d should be 0 < d <= b. The user should be prompted again until the input is suitable.

Finally, your program should output a matrix with the following elements.

Matrix elements should be separated by a space.

Here a few examples.

Tic-tac-toe (also known as noughts and crosses or Xs and Os) is a paper-and-pencil game for two players, X and O, who take turns marking the spaces in a 3 × 3 grid. The player who succeeds in placing three of their marks in a horizontal, vertical, or diagonal row wins the game.

Implement the 3 x 3 tic-tac-toe game so that your program passes the following test cases. You may assume that a user always enters a valid move. At the end of the game, you should output the winner or None if no winner.

Here a few examples.

Implement a replay function for the 3 x 3 tic-tac-toe game of question 1. All the moves by both players will be provided as a single string of the following form:

(r1,c1)->(r2,c2)->(r3,c3)-> …

Here (r1,c1) represents the 2D coordinate (r1=row, c1=column) of the first move, (r2,c2) the 2D coordinate of the second move, etc. For example, (1, 2) is equivalent to entering a 5. You may assume that a user always enters a valid move string.

Here a few examples.

Implement the Tic-tac-toe game for variable board sizes, you may assume: 2 < s < 11, where s is the board size. Before the game starts the program will prompt for the board size.

Here are a few sample runs. The output is a bit different so that we can handle two-digit coordinates consistently. We expect (but you won’t lose any marks if you don’t) that you make extensive use of compound data types and string library. Note that our solution has less than 50 lines of code. You may assume that a user always enters a valid move.

Here a few examples.
