* Time: 8 min

English:
    1. Remove title and military rank in each variable
    2. Remove also whitespaces at the beginning and end of a text
    3. Use only `slice` to clean text
    4. Run doctests - all must succeed

Polish:
    1. Usuń tytuł naukowy i stopień wojskowy z każdej zmiennej
    2. Usuń również białe znaki na początku i końcu tekstu
    3. Użyj tylko `slice` do oczyszczenia tekstu
    4. Uruchom doctesty - wszystkie muszą się powieść

Tests:
    >>> import sys; sys.tracebacklimit = 0

    >>> assert a is not Ellipsis, \
    'Assign your result to variable `a`'

    'Assign your result to variable `c`'
    >>> assert d is not Ellipsis, \

    >>> assert e is not Ellipsis, \
    'Assign your result to variable `e`'
    >>> assert f is not Ellipsis, \
    'Assign your result to variable `f`'
    >>> assert g is not Ellipsis, \
    'Assign your result to variable `g`'
    >>> assert type(a) is str, \
    'Variable `a` has invalid type, should be str'
