Find the height of the tree

You are given an array of length N. The array stores information about an n-ary tree. And the n-ary tree has N-nodes numbered 0 – (N-1).The ith index in the array contains the parent nodes number j. Given this array find the height of the tree. The parent of the root is -1

It would be good to solve this problem in O(n).
