Extracted text: Create an Activity Diagram for the following problem: Select a chocolate, a chips pack and a coke bottle from a vending machine. If the item is available in the machine, add the item to the cart and add the price of the item to total_price. Else, skip that item and add only available items . Pay the total amount of the cart using bills and return the change and exit the transaction. Also answer one of the two below questions for the above example: (a) What classes will you need in a class diagram? How will you connect these classes with implement and inheritance arrows and aggregate and association relationships? Draw a class diagram with the classes you came up with. OR (b) Draw a sequence diagram for the high level operations (you may ignore minor details).
