Model this system as a FSM. Draw a deterministic non-skeletal Finite State Machine model on paper. Put comments on important actions. Give states short useful names. Vending Machine allows users to deposit coins and push a button to dispense product, or a button to cancel and get all deposited money back. 2 separate places: the currentBin and the bank. When product is dispensed currentBin is transferred to bank. On cancel, currentBin is returned. Product is only dispensed if currentBin >= 50 cents. Commands: d (dime), q (quarter), D(dispense),C(cancel
