expected an exit code of 0, not a prompt for input WON

Question

I'm still stuggling with the game of fifteen, and I could make it works. However, when I run check50 it displays

:( 3x3.txt wins the 3x3 board
   \ expected an exit code of 0, not a prompt for input
:( 4x4.txt wins the 4x4 board
   \ expected an exit code of 0, not a prompt for input

Every change I made, I get the same error...
I know that it's an error in my WON function, that keeps prompting for input instead of exit with code 0. But I couldn´t solve it so far...

My code initially was

bool won(void)
{
    // TODO
    int n = 0;
    for (int i = 0; i < d; i++)
    {
        for (int j = 0; j < d; j++)
        {
            n ++;
            if (board[i][j] != n)
            { 
                return false;
            }
        }
    }
    return true;
}

Now, it's

bool won(void)
{
    // TODO

int n = 1; 

for (int i = 0; i < d; i++)
{
    for (int j = 0; j < d; j++)
    {
       if (board[i][j] < board[d-1][d-1])
       {
           if (board[d-1][d-1] == 0 && board[i][j] == n)
           {
               return true;
            }
        }
        n++;    
    }  
}   
return false;
}

I'd be very grateful if you could hint me what I'm doing wrong.

HINT: What is the value of the lower right hand corner tile supposed to be when the game is won? What is your code looking for?
