Problem 1 (150pts): Ants Need Food

Part A: Currently, there is no cost for placing any type of Ant, and so there is no challenge to the game. The base class Ant has a food_cost of zero. Override this class attribute for HarvesterAnt and ThrowerAnt according to the "Food Cost" column in the table below.

	Class	Food Cost	Health
	HarvesterAnt	2	1
	ThrowerAnt	3	1

Part B: Now that deploying cost food of Ant, we need to be able to gather more food! To fix this issue, implement the HarvesterAnt class. A HarvesterAnt is a subclass of Ant that adds one food to the gamestate.food total in its action.

Before writing any code, unlock the tests to verify your understanding of the question:

$ python ok -q 01 -u

Once you are done unlocking, begin implementing your solution. You can check your correctness with:

$ python ok -q 01

Try playing the game by running python gui.py. Once you have placed a HarvesterAnt, you should accumulate food each turn. You can also place ThrowerAnts, but you'll see that they can only attack bees that are in their Place, making it a little difficult to win.
