Wrong answer error

#1

I am getting the right answer for the given testcase but I am facing wrong answer error as I submit.
I have taken the GenericHeap code taught to us and have included all the necessary functions ( also UPDATE PRIORITY ) and for those nodes which have cost as -1 are added in the graph but with NO EDGES. For those isolated nodes I have given the condition that
if( value == Integer.MaxValue )
then print -1 for them.
Please tell me if I am missing something in the question.
