我如何继续，我哪里弄错了？

Question

问题是：

Give numBottles(input) full water bottles, you can exchange numExchange(input) empty bottles for one full water bottle. The operation of drinking a full water bottle turns it into an empty bottle. Return the maximum number of water bottles you can drink. No functions, imports, whatsoever, only list, string, int, loops and that kinda stuff.

Ex.1:

Input(s): numBottles = 9, numExchange = 3 Output: 13 Explanation: You can exchange 3 empty bottles to get 1 full water bottle. Number of water bottles you can drink: 9+3+1 = 13

Ex.2: Input(s) :numbottles = 15, numexchange = 4 Output: 19 Explanation: You can exchange 4 empty bottles to get 1 full water bottle. Number of water bottles you can drink: 15 + 3 + 1 = 19

我得到的是：

    Numbottles = int(input("Numbottles"))
    Numexchange = int(input("NumExchange"))
    total = []
    for i in range(0,Numbottles // Numexchange):
            x = Numbottles % Numexchange
            total.append(x)
    print(sum(total))

Answer 1

请试试这个

Numbottles = int(input("Numbottles"))
Numexchange = int(input("NumExchange"))
total = [Numbottles]
for i in range(0,Numbottles // Numexchange):
        Numbottles = Numbottles // Numexchange
        total.append(Numbottles)
        Numbottles += Numbottles % Numexchange
print(sum(total))
