Consider the below left-left rotation pseudo code where the node contains value pointers to left, right child nodes and a height value and Height() function returns height value stored at a particular node.
What is missing?

avltree leftrotation(avltreenode z):
   avltreenode w =x-left
   x-left=w-right
   w-right=x
   x-height=max(Height(x-left),Height(x-right))+1 
   w-height=max(missing)+1   
  return w

Height(w-left), x-height

Height(w-right), x-height

Height(w-left), x

Height(w-left)

     if(left_tree_height== -1) 
       return left_tree_height
 
     right_tree_height= avl(right_of_root)
 
     if(right_tree_height==-1)
       return right_tree_height

yes
