You act as a worker who had just finished his work at 11:30 p.m. You had to go your home which was on the 11th floor, however, there have been some issues with the stairwell space. You must follow the rules to get to higher floor, else you will return to 2nd floor.

你是一个工作到11点半才回到公寓的职员，需要到11楼的家去。但是公寓的空间好像出现了一点点小问题，你必须遵守规则才能去到更高楼层，否则就会回到2楼。

RULES 规则:

1、The 2nd floor is always normal. 2楼永远是正常楼层。

2、If there is any differences between current floor and 2nd floor (lights excluded), please go downstairs. 如果当前楼层与2楼有任何不同（灯光除外），请下楼。

3、If current floor is the same with 2nd floor (lights excluded), please go upstairs. 如果当前楼层与2楼没区别（灯光除外），请上楼。

4、The lights can be off or flashing, those are normal. 灯光可能闪烁甚至熄灭，不属于异常。
