A vending machine accepts coins whose values sum to the price of a product or whose sum exceeds the purchase price by one coin of any denomination. The vending machine then accepts either a coin release button press that releases the inserted coins (for example, if the customer decides not to buy) or a button press to release the product and any required change, then resets the machine to a “start state.” The vending machine owner can remove money, increase change in storage, or resupply the products on an as-needed basis. Write a design and code the corresponding program that models this situation.
