Not geeting the exact output

Modified code

Your mistakes

  1. if(k==0){

     // cout<<root->data<<" ";

 temp.push_back(root->data);

 return 0;

    }
    add this condition in node_at_distance_k()

  2. if dr or dl !=-1 then call print function not node_at_distance_k()

  3. don’t print the required nodes because output should be in sorted order hence first store all possible answers in a vector and then print them after sorting

  4. if size of temp is 0 means no element found then print 0
