Print all Nodes at distance k from a given node

#1

My code is giving two wrong test cases. Can you please help me to find the problem?

#2

@avijuneja2007 print all nodes in sorted format (so put them in a vector and then sort them).

#3

Still one test case is wrong !!

#4

You have to print 0 when there is no node at distance k(or v.size() is 0).
