Solution in Ruby (2.3.3) (judge verdict: Runtime Error)

today = gets().chomp.to_s
# weathers = "Sunny,Cloudy,Rainy".split(",")

# return if today.empty?
# weathers.index(today) == weathers.size() -1 ? index = 0 : index = weathers.index(today)+1

# p weathers[index]


return p "Cloudy" if today == "Sunny"
return p "Rainy" if today == "Cloudy"
return p "Sunny" if today == "Rainy"
