### You are given a tree T = (V;E) along with a designated root node r 2 V . The parent of any node v 6= r , denoted p(v), is de ned to be the node adjacent to v in the path from r to v. By convention, p(r) = r. For k > 1, de ne pk(v) = pk????1(p(v)) and p1(v) = p(v) (so pk(v) is the kth ancestor of v). Each vertex v of the tree has an associated non-negative integer label l(v). Give a linear-time algorithm to update the labels of all the vertices in T according to the rule lnew(v) = l(pl(v)(v)).
