In this question we will design a vending machine with some fictitious coins. Assume the vending machine accepts the following two coins. Coinl (C1): 10 cents Coin2 (C2): 25 cents The machine accepts one coin at a time. The vending machine sells two products: a gum for 20 cents and a cup of tea for 35 cents.

Question
In this question we will design a vending machine with some fictitious coins. Assume the
vending machine accepts the following two coins.
Coin1 (C1): 10 cents
Coin2 (C2): 25 cents
The machine accepts one coin at a time. The vending machine sells two products: a gum for
20 cents and a cup of tea for 35 cents. The machine also has a buy button (B).
(Tea price =< money ) If the total deposited money is equal or higher than the Tea price,
the machine automatically dispenses a cup of tea and returns the change (if any).
(Gum price =< money < Tea price) If the total deposited money is equal or higher than the
Gum price but less than the Tea price and the buy button is pressed,
the machine dispenses the Gum and returns the change (if any).
(money < Gum price) If the total deposited money is less than the Gum price and the buy
button is pressed,
the machine returns the change (if any).
So, the inputs and outputs are
Inputs
Outputs
Coinl (C1)
Tea (T)
Coin2 (C2)
Gum (G)
Buy Button (B)
Return Change(R)
a) Clearly define your states for a Mealy FSM.
b) Draw the state diagram for a Mealy FSM.
