Automatic Newspaper Vending Machine Finite Automata (DFA or FA).

Case Study 1 of Newspaper Vending Machine DFA Finite Automata

Suppose you need to design a Deterministic Finite Automata for Newspaper Vending Machine. You need to insert only three coins. Suppose our language has three alphabets {1,2 5}. Detail of coins: You have only three types of coins.

1. Coin of 1 Rupee
2. Coin of 2 Rupee
3. Coin of 5 Rupee

The machine only accepts a total of 7 Rupees. If 7 Rupee coins are inserted into the machine then machine allows you to get the newspaper. The person who gives a total of 7 Rupee coins to the machine, can only get the newspaper from the machine.

1. Coin of 1 Rupee
2. Coin of 2 Rupee
3. Coin of 5 Rupee

If 7 Rupee or more than 7 rupee coins are inserted into the machine then machine allows getting the newspaper. The person who gives a total of 7 Rupee or more than 7 rupee coins to the machine, can only get the newspaper from the machine. It is important to note that if the user inserted the coins of more than 7 rupee worth, then the machine accepts the coins and does not return the remaining amount to the customer.
