# 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)

```
