Farm

A Farm contains a list of crops.

• You can add crops to the farm by calling the void plant(String crop) method.
• You can harvest a lot of crops at once by calling the int harvest(List<String> crops) method - this method returns the number of individual crops harvested.
• When you void fertilize(String crop), the grows more — represent that by putting another one of the same crop next to every crop you find in the current list of crops.

Example

A Farm has corn, corn, corn, soybeans, soybeans, and green beans.

• Calling the plant("wheat") method adds wheat to the list of crops.
• Calling the harvest(["corn","soybeans"]) method removes corn and soybeans from the list of crops and returns 5, since 5 items were harvested. The farm now has: green beans.
• Using the original example farm, fertilize("soybeans") makes the farm have corn, corn, corn, soybean, soybeans, soybeans, soybeans, and green beans.
