Return the root of the updated binary search tree. Here is the pseudocode for deletion in a binary search tree: function deleteNode(root, value): if root is NULL: return root if value < root->data: root->left = deleteNode(root->left, value) else if value > root->data: root->right...
Write 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(object): def __init__(se...

will do it later
The value of a parent node is bigger than all values of its left sub tree. The value of a parent node is smaller than all values of its right sub tree. The following is an example of BST: Binary Search Tree If we want to delete a node from BST, we basically have 3 different situ...
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 the problem into case 2 ...
Thetwalksubroutine steps through the binary search tree whose root is pointed to by theRootPointerparameter. (Any node in a tree can be used as the root to step through the tree below that node.) TheActionparameter is the name of a routine to be invoked at each node. The routine specif...
