                    Tic Tac Toe

  This is a terminal game for two users. User need to input row number and
  column number to make a draw. Both are within range [1-3]

  When the game starts, it's user1's turn,

     1  2  3
    ----------
  1 |  |  |  |
    ----------
  2 |  |  |  |
    ----------
  3 |  |  |  |
    ----------

  For example, user1 can input 
               row:2
               column:3, to make a draw as following
     1  2  3
    ----------
  1 |  |  |  |
    ----------
  2 |  |  | X|
    ----------
  3 |  |  |  |
    ----------
    
  Now it come to user2's turn. If user2 wants to make a draw at 
      row:3 
      column:1, the board will be changed as following:

     1  2  3
    ----------
  1 |  |  |  |
    ----------
  2 |  |  | X|
    ----------
  3 | O|  |  |
    ----------


  Several warnings:
  
  1. Users can't make a draw at the cell where it is already occupied
  2. Users must enter a number within range 1 to 3. Any other characters
     such as ./#$%^&FGZsefef will reprompt the instructions.
