Otherwise, the current state is updated and the process is repeated. Draw a state machine that models the above vending machine on a piece of paper, then answer the following question:If the vending machine is at the waiting state and the user continues to deposit money, what does the given vending machine do$?$Group of answer choicesThe vending machine moves to ready state.The vending machine updates the balance.The vending machine moves to the refund state.The vending machine may either trigger an error or ignore the deposit.
