Description
The vending machine in Hsin Dorm is stuck. The vending machine owner does not want to deal with it anymore, and let you tinker with it. You, being a smart CS student, will create a VendingMachine class so that the vending machine can run better than before.
Given this code:
class Item:
def __init__(self, price: int, stock: int):
self.price = price
self.stock = stock
def __init__(self, balance: int):
self.items = {}
self.balance = balance
self.initial_balance = balance
# Continue the class
# ----- input output handler -----
line = input().split()
T = int(line[0])
initial_balance = int(line[1])
machine = VendingMachine(initial_balance)
for _ in range(T):
parts = input().split()
cmd = parts[0]
if cmd == "BUY":
name, qty = parts[1], int(parts[2])
machine.buy(name, qty)
elif cmd == "RESTOCK":
name, price, qty = parts[1], int(parts[2]), int(parts[3])
machine.restock(name, price, qty)
print(machine)
You will need to implement VendingMachine class so that it has 2 methods:
1) BUY
- Customer buys {qty} of {name}. If a customer buys more than the current available stock, print
no stock. - Customer will NOT try to buy something that has never been stocked.
2) RESTOCK
- You restock {name} by {qty} and update the price with {price}. This will cost (price x qty / 2) of your balance. If you are trying to restock more than you can afford, print
you dont have money
You can create any additional functions that you think might be needed.
> Note: the grammar error at dont (not don't) is on purpose
Input
The first line consists of 2 integers:
- The first integer T will be the number of operations on that day
- The second integer N will be the initial balance you get.
The next T line will be one of these commands in this format:
- BUY {name} {quantity} where {name} is the name of the item that the customer buys and
{quantity} is how many items the customer buys
- RESTOCK {name} {price} {quantity} where {name} is the name of the item that you want to restock, {price} is the price that you want to sell that item and {quantity} is how much you restock that item
Output
Output the profit you get after all T operations done. (Profit = Final Balance - Initial Balance)
