English:
    1. Calculate altitude in kilometers:
        a. Kármán Line Earth: 100_000 m
        b. Kármán Line Mars: 80_000 m
        c. Kármán Line Venus: 250_000 m
    2. In Calculations use floordiv (`//`)
    3. Run doctests - all must succeed

Polish:
    1. Oblicz wysokości w kilometrach:
        a. Linia Kármána Ziemia: 100_000 m
        b. Linia Kármána Mars: 80_000 m
        c. Linia Kármána Wenus: 250_000 m
    2. W obliczeniach użyj floordiv (`//`)
    3. Uruchom doctesty - wszystkie muszą się powieść

References:
    * Kármán line (100 km) - boundary between planets's atmosphere and space

Hints:
    * 1 km = 1000 m
    * Use // to get floor division as int

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