Tank Sorting
============

Again in the context of the water tanks from the previous problem, you are required to deliver the following sorting functions in the module :mod:`tank_sorting` (file :file:`tank_sorting.py`).

------------------------------------------------------------------------------------------------

The first function is:

    .. py:function:: tank_sort_1(tL)

such that

    **given** *tL* a :class:`list` of of water tank info as described above

    **returns** a copy of *tL* but where that the tanks are ordered by placing first the tanks with more water contributions. In case of a tie the order in Lt is maintained.

For example:

    .. literalinclude:: tank_sort_1.test
        :language: python3
        :start-after: --ini
        :end-before: --fi

Doctests are available in the :download:`tank_sort_1.test` file.

------------------------------------------------------------------------------------------------

The second function is:

    .. py:function:: tank_sort_2(tL)

such that

    **given** *tL* a :class:`list` of water tank info as described above

    **rearranges** *tL*  by placing first the tanks with higher capacity. The tanks with the same capacity must be alphabetically ordered.

For example:

    .. literalinclude:: tank_sort_2.test
        :language: python3
        :start-after: --ini
        :end-before: --fi

Doctests are available in the :download:`tank_sort_2.test` file.
