Deletion in a binary search tree can be divided into three cases: 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...
Given a root node reference of a BST and a key, delete the node with the given key in the BST. Return the root node reference (possibly updated) of the BST. Basically, the deletion can be divided into two stages: Search for a node to remove. If the node is found, delete the node...
case 1: if the delete node is leaf node, then we can simply remove it case 2: if the delete node is has single side or substree case 3: it has two children, then to keep it as a valid binary search tree, we can copy the min value from right subtree to delete node, to convert...

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...

If the node is found, delete the node. Note: Time complexity should be O(height of tree). Example: root = [5,3,6,2,4,null,7] key = 3 5 / \ 3 6 / \ \ 2 4 7 Given key to delete is 3. So we find the node with value 3 and delete it. ...
