def judge(tester_lowest: int, tester_highest: int, song_lowest: int, song_highest: int) -> list:
    """
    To determine the lowest and highest pitches of the given song is beyond that of the tester.
    Parameters
    ----------
    tester_lowest: int
        The midi integer represent the lowest pitch of the tester.
    tester_highest: int
        The midi integer represent the highest pitch of the tester.
    song_lowest: int
        The midi integer represent the lowest pitch of the song.
    song_highest: int
        The midi integer represent the highest pitch of the song.
    Returns
    -------
    out: list
        The function returns True if the tester can handle the song. Otherwise, return False.
        The list represents as [low pass, high pass].
