Help me to understand the given second test case

#1

why is it not 12 6.
given o/p is -1 6

#2

There are 3 nodes in the graph, but only one edge from 2 to 3.
Therefore distance between 2 and 3 is 6.
Now 1 is disconnected from both 2 and 3 ,hence its distance from 2 is -1.

#3

what’s wrong in my code? https://ide.codingblocks.com/s/297254

#4

I see that ans for second case should be -1 6 only.
Where do you face the problem in understanding this.
