Anyone know what does the Problem 58. Tic Tac Toe FTW in cody mean?

Given a tic tac toe board:

1 represents X

0 represents empty.

-1 represents O

It is X's move. If there is an immediate win possibility, choose a square for an immediate win. Otherwise return 0.

Return absolute index of the square of choice. If multiple square are valid, return them in order.

Example:

 Input  a = [ 1  0  1
             -1  1  0
              0 -1 -1]
 Output wins is [4 8]

Can anyone explain it in detail?

I'm confused with the sentence I marked ans bold style.

Thanks a lot~~~

Unlocking answers to last Cody problem?

I've written a valid answer to the last Cody problem, but it is not even close to the best answer. I have no idea how they made this short answer. To unlock it I need to solve another Cody question, but there are none left... :(

Anybody know how to unlock the last question?

Cody: Problem 30 - function Sortrows

Hi,

i'm "solving" number 30 cody's problem.

I think to solve that whit sortrows function.

If I have a z vector:

j = sqrt(-1);
z = [-4 6 3+4*j 1+j 0];

my funtion is:

function z = complexSort(z)
    z(2,:)=sqrt(real(z).^2+imag(z).^2);
    z=sortrows(z',-2);
    z=z(:,1);
end

End it return the result

z =

   6.0000             6.0000          
   3.0000 - 4.0000i   5.0000          
  -4.0000             4.0000          
   1.0000 - 1.0000i   1.4142          
        0                  0

The question is: why imagine part in input is positive e sortrows trasform it in negative?

best regards

Marco

What matlab easter eggs do you know?

Please post the easter eggs that you have found so far if they aren't already posted by someone else.

Let's try to make a good Matlab easter egg list because it seems that there isn't one.

What should be posted:

Unexpected but intentional behaviour
Special things that the programmers left for us to discover
Extra code inside a function that can be used for other purposes
Hidden pictures and audio clips

What shouldn't be posted:

Repeated Easter Eggs, if someone already posted it please don't repeat
Bugs in functions that cause trouble and might be fixed in later versions
Matlab games that come with the program unless they aren't mentioned in the documentation (the games are in the other demos, try the xpbombs and fifteen, you can even see the code for both games)
