Specs

Provide the functional design of software that controls a Vending Machine. The Vending Machine has a predefined set of items that the user can purchase using cash. The vending machine has the following actions:

• User inserts cash
• User selects item
• Item is dispensed if enough money has been inserted
• Change is dispensed
• Coin denominations accepted:
  • Quarter = 25 cents
  • Dime = 10 cents
  • Nickel = 5 cents
  • Penny = 1 cent

The first two actions shoud be allowed in any imaginable order, for example:

• User may select item first, then insert enough coins to dispense it.
• User may insert enough coins, then select an item.
• 👆 And any combinations of these 2 actions.
  • If they select a different item after they've already inserted some coins, the "Sale Price" should change to that item. They should be required to insert that much money. They can select a different item as many times as they want.

Your Task

1. Write a program that emmulates the Vending Machine.
2. Choose whatever input method you prefer. CLI is fine, or simulated input from a Test.
3. Implement a method dispense_change()
