I will rate the answer , Thank you.

2. Tic-tac-toe. Write a program to play tic-tac-toe. For now, the interface will be minimal: you wil ask the user for a number (a square) between 1 and 9, and pick one in return. You must make a legal move, and detect when one of you wins. Your gamestate data structure (the way you internally represent the board) should be a nine-element array with empty squares as zero, X (human player) spaces are marked with +1, O (computer) with -1. a. Write a function that asks the user for a move and makes sure it is legal. The input and output should be the gamestate. Show 3 test runs. b. Write a function that determines if either the computer or player has won (return 1 for player, 0 for no winner, -1 for computer). Show 3 test runs. Write a function that detects if any valid moves remain. Show 3 test runs. Write a function that supplies a computer guess. It can be random or sophisticated - your c. d. choice. Show 3 test runs. e. (optional) Write a script that initializes the board and uses a while loop to string together your functions until the game has been won or drawn. Play!

Explanation / Answer

a.

  
gamestate1 = [[0 0 0]
[0 0 0]
[0 0 0]];

gamestate2 = [[1 1 1]
[0 0 0]
[0 0 0]];

gamestate3 = [[-1 -1 -1]
[1 1 1]
[1 1 1]];

function state =play(state)

valid=false;
while (valid==false)
row = input("enter valid row ");
col=input("enter valid column");

if(row>=1 && row<=3 && col >=1 && col<=3)

if(state(row,col)==0)
state(row,col)=1;
valid=true;
end

end

end

end

disp(play(gamestate1))
disp(play(gamestate2))
disp(play(gamestate3))

--------------------------------

b.

  
gamestate1 = [[0 0 0]
[0 0 0]
[0 0 0]];

gamestate2 = [[1 1 1]
[0 0 0]
[0 0 0]];

gamestate3 = [[-1 -1 -1]
[0 0 0]
[0 0 0]];

  
% The won function calculates if the current game state is in a winning

function won = won(state)
% Horizontal
  
if (state(1,1) == state(1,2) && state(1,1) == state(1,3) && state(1,1) ~= 0)

won=0;
  
end
end

disp(won(gamestate1))
disp(won(gamestate2))
disp(won(gamestate3))

----------------------------------

c.

  
gamestate1 = [[0 0 0]
[0 0 0]
[0 0 0]];

gamestate2 = [[1 1 1]
[0 0 0]
[0 0 0]];

gamestate3 = [[-1 -1 -1]
[1 1 1]
[1 1 1]];

%returns 1 for true
%-1 for false
function out =validMoveRemaining(state)

out=-1;

for i = 1:size(state,1)
for j = 1:size(state,2)
if(state(i,j)==0)
out=1;
return
end
end
end   
  

end

disp(validMoveRemaining(gamestate1))
disp(validMoveRemaining(gamestate2))
disp(validMoveRemaining(gamestate3))

d.

  
gamestate1 = [[0 0 0]
[0 0 0]
[0 0 0]];

gamestate2 = [[1 1 1]
[0 0 0]
[0 0 0]];

gamestate3 = [[-1 -1 -1]
[1 1 1]
[1 1 1]];

function state =computerGuess(state)

valid=false;
while (valid==false)
A = 1; B = 3;
row = (A-1) + (B-(A-1))*rand(1);
row = floor(row) + 1;

col = (A-1) + (B-(A-1))*rand(1);
col = floor(col) + 1;

if(row>=1 && row<=3 && col >=1 && col<=3)
