Min and Max Swapping
====================

You are required to deliver the following function in the module :mod:`minmax_swap` (file :file:`minmax_swap.py`):

    .. py:function:: minmax_swap(l1, l2)

such that

    **given** *l1*, *l2* :class:`list` s of :class:`float` not necessarily of the same length.

    **modifies** them both by swapping their values at every position in the range of both, such that the bigger numbers end up in  ``l1`` and the smaller ones in ``l2``. The values in positions where only one list is defined should remain unchanged.


For example:

    .. literalinclude:: minmax_swap.test
        :language: python3
        :start-after: --ini
        :end-before: --fi

Doctests are available in the :download:`minmax_swap.test` file.
