Java.

Starter code:

import java.util.*;

public class PoD {

public static boolean validateBoard(String[][] gameBoard) {

boolean validBoard;
//PLEASE START YOUR WORK HERE

//PLEASE END YOUR WORK HERE
return (validBoard);
}

public static void main(String[] args) {

//Instantiate new scanner to read from the console.
Scanner in = new Scanner( System.in );
int gamePiece;

String[][] ticTacToeBoard = new String[3][3];

for (int i=0; i<3; i++)
{
for (int j=0; j<3; j++)
{
//Read in board

ticTacToeBoard[i][j] = in.next();

//Output board
if (j<2)
{
System.out.print(ticTacToeBoard[i][j] + " ");
}
else
{
System.out.println(ticTacToeBoard[i][j]);
}
}
}

if (validateBoard(ticTacToeBoard)) {
System.out.println("Valid board");
}
else {
System.out.println("Invalid board");
}
}
}

Instructions
You are going to write a method (to be called validateBoard ] that is going to validate whether or not a Tic-Tac-Toe board is possible. Tic-Tac-Toe is played on a 3 by 3 board and players take turns placing either an x or an o on the board. We will assume
that in Tic-Tac-Toe, the player placing x will go first and that o will go second. Learn more about the game here: https://en.wikipedia.org/wiki/Tic-tac-toe
As the player placing x pieces goes first, and play alternates, a valid board is one in which there is either the same number or one more x game pieces on the board as there are o game pieces.
The board is represented by a 3 by 3 array that holds strings that represent the game piece at each location. A space can hold any of the following:
• "x", representing an x game piece in that position
"o", representing an o game piece in that position
".", representing an empty position on the board
Write the body of the program.
Details
The main method of the program has been completed for you. You are to create the method called validateBoard which is called from the main method. The validateBoard method should take a 2D array as input and return a boolean value. Details of
this method are below:
Input
The valldateBoard method should take as input:
- a 2-dimensional array that holds strings (representing the 3 by 3 game board where strings "x", "o" and "." denoting the game piece in each location, as described above)
Processing
The new method will decide whether the incoming 2D array is represents a valid board. A valid board is defined to be a board in which there are either the same number of x as o game pieces, or one more x than o.
Output
If the board is determined to be valid, the method will return a boolean value of true. Otherwise, it will return false.
