Did not clear all test cases…why???

#2

hi… so there are 2 faults in ur soln.
if (root == target)
{
// this return the nodes at distance k in sub-tree.
NodeAtK(root, k);
return 0;
}

firstly yha return 0 hoga… not 1…
secondly jo ans hai use ek vector mei store kro…
then at the end sort krke print kro… if vector size is zero then print 0 as the o/p
