Question 1 (Points: 12.0): Modify an Inventory Class

Given the Inventory class below, modify it to:

• Add an __init__() method that initializes the name and stock attributes. The stock attribute should default to 0.

• Add an add_stock(quantity) method that increases the stock attribute.

• Add a remove_stock(quantity) method that decreases stock but ensures it doesn’t go below zero.

• Implement a __str__() method that returns "Product: <name>, Stock: <stock>".

Example:

item = Inventory("Gears", 50)
item.add_stock(20)
print(item)  # Output: Product: Gears, Stock: 70
item.remove_stock(80)
print(item)  # Output: Product: Gears, Stock: 0

...

# Example usage
item = Inventory("Gears", 50)
item.add_stock(20)
print(item)
item.remove_stock(80)
print(item)
