def swine_swap(score):
    """Return whether the players' scores will be swapped due to Swine Swap.

    score:           The total score of the current player.

    Hint: for this problem, you will find the math function sqrt (i.e., square root) useful.
    >>> sqrt(9)
    3.0
    >>> floor(sqrt(9))
    3
    >>> floor(sqrt(8))
    2

    # BEGIN PROBLEM 4
    return floor(sqrt(score)) ** 2 == score
