Sorry, have'nt seen your reply such a long time:
static int height(Node root) { if(root == null) return 0; //some code then
My code returns 0 when root is NULL and I had no problems with it. Maybe it was fixed later.
Yeah thats not correct. Should return -1 if root is null and 0 if there is a root with its left and right null.
