燈制
[size=4]有兩間屋，
一間甲，一間乙，
甲屋有三個燈制，
乙屋有三個燈泡，
甲屋是看不到乙屋，
而甲屋的每一個燈制是控制乙屋的其中一個燈泡，
問你怎樣可以只停留在甲屋一次，
停留在乙屋一次，
而可以知道那個燈制是控制那個燈泡呢?

First, switch on one of the light bulb A.
After 10 mins, switch light bulb A off.
Then, switch on light bulb B.
Go to Room B:
The bulb which is switched off but with a high temperature must be bulb A.
The bulb which is switched on is B.
The remaining bulb must be C.
