In this exercise, you will create a class NoughtsAndCrosses which will represent a noughts-and-crosses board.

Implement a class NoughtsAndCrosses with the following API:

public NoughtsAndCrosses(int[][] board)

Class constructor. The board will be passed as a \( 3 \times 3 \) two-dimensional array of ints. Each element of the array contains a number representing what is in that cell:

• 0 : nothing
• 1 : a nought
• 2 : a cross

public boolean isDraw

Returns true if neither player won, even if the game is not complete. Otherwise, if a player has three noughts or crosses in a line, returns false.

public int whoWon

Returns a 1 if there are three noughts in a line, and a 2 if there are three crosses in a line. Otherwise returns 0.

The following client code illustrates how the game works.

int[][] board = { { NONE, NONE, NOUGHTS },
                  { NONE, NONE, NOUGHTS },
                  { NONE, NONE, NOUGHTS }, };

NoughtsAndCrosses nc = new NoughtsAndCrosses(board);

System.out.println(nc.isDraw()); // false
System.out.println(nc.whoWon()); // NOUGHTS
