I want to ask a interesting question about this problem.

In the sample input:
It is said that 3 is 5's child,and 3 is 4's child,and 5 is 4's child.
It is an illegal relationship in the realistic, isn't it?
It seems that 5 is 4's child,and 5 and 4 are 3's parents!

Maybe Martians don't think that it is strange. :)
