--description--

Given two star sign strings, return their compatibility percentage.

The signs are arranged in a wheel of 12 positions in this order: "Aries", "Taurus", "Gemini", "Cancer", "Leo", "Virgo", "Libra", "Scorpio", "Sagittarius", "Capricorn", "Aquarius", "Pisces", wrapping back to "Aries" after "Pisces". Find the shortest distance between the two signs and return the compatibility:

Distance	Compatibility
0	"100%"
1	"40%"
2	"80%"
3	"30%"
4	"90%"
5	"20%"
6	"50%"

--hints--

horoscopeMatch("Libra", "Sagittarius") should return "80%".

assert.equal(horoscopeMatch("Libra", "Sagittarius"), "80%");

horoscopeMatch("Gemini", "Scorpio") should return "20%".

assert.equal(horoscopeMatch("Gemini", "Scorpio"), "20%");

horoscopeMatch("Pisces", "Aries") should return "40%".

assert.equal(horoscopeMatch("Pisces", "Aries"), "40%");

horoscopeMatch("Capricorn", "Cancer") should return "50%".

assert.equal(horoscopeMatch("Capricorn", "Cancer"), "50%");

horoscopeMatch("Aquarius", "Aquarius") should return "100%".

assert.equal(horoscopeMatch("Aquarius", "Aquarius"), "100%");

horoscopeMatch("Virgo", "Taurus") should return "90%".

assert.equal(horoscopeMatch("Virgo", "Taurus"), "90%");

horoscopeMatch("Leo", "Scorpio") should return "30%".

assert.equal(horoscopeMatch("Leo", "Scorpio"), "30%");
