    how it works?

      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.
