4. Delete Node in BSTWrite a Python program to delete a node with the given key in a given binary search tree (BST).Note: Search for a node to remove. If the node is found, delete the node.Sample Solution: Python Code:# Definition: Binary tree node. class TreeNode(objec...
and delete the node P. To delete 3 in Figure 4, just set its parent's right-child field to Zero, and delete the node P. So We need to know node P is its parent's right child or left child. However, If Node p is tree's root nood, just delete the root nood. ...

The node to be deleted is a leaf node: If the node to be deleted is a leaf node, it can simply be removed from the tree. The parent node of the deleted node must have its corresponding child pointer set to NULL to reflect the change in the tree. The node to be deleted has only...
