I need to implement remove part in bst. In this piece of python code. I understand that there are four or three cases such as root; right Child or left child or both child. When we remove we still have to keep balanced property of bst. I am having problem implementing it. And call it in driver class. Thank you for help.

class BST: class Node: def init self, item, left, right): self. itemitem self. left = left self-right right def init_ _(self): self. root None def isEmpty(self): return self._root is def clear (self) self. root = None # def remove (self, item): To Do: def insert (self, item): self'-root self-insert (self..-root, item) = def insert (self, root, item): if root is None: elif item
