Case20. Two integers are given: D (day) and M (month), which determine the correct date. Output the sign of the Zodiac corresponding to this date: Aquarius (20.1-18.2), Pisces (19.2-20.3), Aries (21.3-19.4), Taurus (20.4-20.5), Gemini (21.5-21.6 ), Cancer (22.6-22.7), Leo (23.7-22.8), Virgo (23.8-22.9), Libra (23.9-22.10), Scorpio (23.10-22.11), Sagittarius (23.11-21.12), Capricorn (22.12-19.1).

Solution in Python 3:
