There are five employees—G, H, I, J, and K—in an office. Rumors spread through the office according to the following rules; Rumors can be passed in either direction between J and K. Rumors can be passed from G to H, from H to I, and from I to K. A rumor begun by H that reaches J will be known by all the following employees EXCEPT?

参考解析

解析:
这题看起来挺麻烦,其实很简单,H会把传言告诉I,I告诉K,K再告诉J,因此最后只有G不会听到这个传言。
