you have been given tree, find a shortest path to travel from 1 to N, such that you visits some given set of nodes in your path from 1 to N. you are allowed to visit same node multiple times.

eg — N = 5 

1
      / \
    2     3
         / \ 
        4   5

node_to_visit_in_path = { 2 ,4 } solution — 6 ( 1 -> 2 -> 1 -> 3 -> 4 -> 3 -> 5)

is this a famous kind of problem ?, i think similar problem i have see somewhere.
