For every one pound of okra you need a minimum of one quart of cooking oil to fry the okra. However, you have a very strange fryer that only accepts oil on whole gallon amounts. So to fry 1, 2, 3, or 4 pounds of okra, you need ONE WHOLE GALLON of oil. To fry 5 pounds, you really only need 5 quarts, but because of your strange fryer you have to use two gallons. Given the number of pounds of okra you want to fry, return how many gallons of oil you need to put in your fryer.
