Vending Machine 🥤🤖

This project emulates a vending machine using Python, implementing functions and matrix concepts to manage the products and transactions. This project was created for the Algorithmic Logic course during the first semester of the Bachelor's in Computer Science at PUCPR. It leverages matrix operations and uses methods within classes to manage the vending machine's functionalities.

Features

• Purchase a beverage by inserting Brazilian currency notes and coins.

• Default available beverages:

  ID	Product	Price	Stock
  1	Coca-cola	3.75	2
  2	Pepsi	3.67	5
  3	Monster	9.96	1
  4	Coffee	1.25	100
  5	Redbull	13.99	2

• Validates the availability of the chosen beverage and ensures payment is enough.

• Calculates and returns the change using the fewest possible notes and coins.

• Dynamically updates the stock after each purchase.

User Instructions

1. The machine awaits the customer to select a beverage by entering its code.
2. The customer is prompted to insert money until it matches or exceeds the beverage price.
3. The machine will calculate and return the change, specifying the notes and coins given.
