2018-4: What's Your Sign?
The Chinese animal zodiac is a repeating cycle of 12 years, with each year being represented by an animal. 2018 is the year of the dog. The signs for the last 12 years are:
| 2018 | Dog | 2012 | Dragon | |
| 2017 | Rooster | 2011 | Rabbit | |
| 2016 | Monkey | 2010 | Tiger | |
| 2015 | Goat | 2009 | Ox | |
| 2014 | Horse | 2008 | Rat | |
| 2013 | Snake | 2007 | Pig |
Note that the year 1 AD (represented as 1) follows the year 1 BC (represented as ¯1) with no intervening "0" year.
Write a function that, given a scalar integer year, returns a character vector (string) of the Chinese zodiac sign for that year. For the purposes of this problem, assume that each year number corresponds to exactly one Chinese zodiac animal.
