# Tessellate S.T.E.M.S (2019) - Computer Science - College - Set 2 - Subjective Problem 2

Suppose your nearest movie theater is showing two movies - Gangs of Wasseypur(which costs 700 rupees per ticket) and The Avengers(which costs 500 rupees per ticket). Consider a kiosk which can dispense at most 3 tickets of same movie at a time. The kiosk follows the following procedure:

1. Asks you to choose the movie.
2. Asks you the number of tickets you want for the movie(Recall that max limit is 3).
3. Asks you to insert the corresponding amount(It can only accept Rs. 100, Rs. 200 and Rs. 500 bills). If excess amount is inserted, the machine returns the excess.
4. Stops accepting money as soon as it has the exact corresponding amount, and dispenses the tickets.

The given description is incomplete, and does not mention what are the states and what are the actions. Attempt to define it precisely, and design a finite state diagram to represent the kiosk. For each action, assign a capital letter of the Latin alphabet, and design a program which takes a string over that alphabet and returns the name of state the system reaches on execution of the sequence of the corresponding actions.

Can you construct a finite state diagram to represent a kiosk which can dispense any number of tickets at once? If yes, give the construction. Explain why not, otherwise.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
