Switch minimum and maximum
==========================

Write the **modifier** function :py:func:`min_x_max` that takes an
homogeneous list, and modifies it by switching its maximum element
with its minimum element. Suppose that the list is not empty and does
not have repeated elements.

Save the function into the file named :file:`switch.py`.  The function
must pass the following doctest:

.. literalinclude:: test-switch.txt
   :language: python3
   :lines: 3-16

.. note:: 

   More tests are provided in the
   :download:`test-switch.txt<test-switch.txt>`.

.. rubric:: Solution

A solution of these functions is provided in the :download:`switch.py <solutions/switch.py>`
