糖纸换糖优惠计划

The chocolate shopkeeper has an excellent recycling policy:

巧克力店老板推出了一个巧克力包装的回收政策 ：
1、I gives you 1 chocolate per every RMB you give him.
你每给我一元，我就给你一块巧克力。

2、He gives you 1 chocolate per every 3 wrappers you give him.
你每给我3个包装纸，我就送你1块巧克力。

rmb =100
wrappers =0
eaten =0

while rmb >0:
    rmb -=1
    eaten +=1
    wrappers +=1

    if wrappers ==3:
        wrappers -=3
        eaten +=1
        wrappers +=1
print("Answer:", eaten)
