It's another beautiful day on Farmer John's farm.

After Farmer John arrived at his farm, he counted $n$ legs. It is known only chickens and cows live on the farm, and a chicken has $2$ legs while a cow has $4$.

What is the minimum number of animals Farmer John can have on his farm assuming he counted the legs of all animals?
