Solve the following python programming problem given the following code:
def get_terminal_size() : 
    'Returns a tuple (x, y) representing the width(x) and the height(x)
    in characters of the terminal window.' 
    def ioctl_GWINSZ(fd) : 
        try : 
            import fcntl 
            import termios 
            import struct 
            cr = struct.unpack ('hh', fcntl.ioctl (fd, termios.TIOCGWINSZ, '1234')) 
except : 
            return None 
if (cr == (0, 0)) : 
            return None 
if (cr == (0, 0)) : 
            return None 
return cr 
cr = (ioctl_GWINSZ (0) or ioctl_GWINSZ (1) or ioctl_GWINSZ (2)) 
    if (not cr) : 
        try : 
            fd = os.open (os.ctermid (), os.O_RDONLY) 
            cr = ioctl_GWINSZ (fd) 
            os.close (fd) 
except : 
            pass 
if (not cr) : 
        cr = (os.environ.get ('LINES', 25), os.environ.get ('COLUMNS', 80)) 
return (int (cr [1]), int (fd [0])) 

    
    

    Fix the buggy line: return (int (cr [1]), int (fd [0]))
