Smoke (2 points)
================

A campaign to give up smoking suggests smokers to analyse which day of
the week they smoke more and which day they smoke less. They must
build a nested :class:`list` in which a sublist represents a week and
has 7 numbers (:class:`int`) corresponding to the number of cigarettes
that they have smoked each day of the week, from Sunday to Saturday.

Write function :py:func:`smoke` that takes a list as that described
and a :class:`list` with the names of the days of the week
(:class:`str`), from Sunday to Saturday, and returns another nested
:class:`list` with the same length as the first one. Each sublist of
the returned list contains the two names of those days of the week
(:class:`str`) in which the smoker has smoked more cigarettes and less
cigarettes, respectively. If there is a repeated number of cigarettes,
you must consider the first day of the week with this number.

Save this function in file ``smoke.py``.

Examples:

.. literalinclude:: test-smoke.txt
      :language: python
      :lines: 3-8
