Consider the pseudo code below.
Does the below code can check if a binary search tree is an AVL tree?

int avl(binarysearchtree root):
     if(not root)
       return 0
     left_tree_height = avl(left_of_root)
 
     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
