In this challenge, a farmer is asking you to tell him how many legs can be counted among all his animals. The farmer breeds three species:
chickens = 2 legs
cows = 4 legs
pigs = 4 legs
The farmer has counted his animals and he gives you a subtotal for each species. You have to implement a function that returns the total number of legs of all the animals.
