How to delete a node from a tree?
When we delete a node, three possibilities arise. 1) Node to be deleted is leaf: Simply remove from the tree. 3) Node to be deleted has two children: Find inorder successor of the node. Copy contents of the inorder successor to the node and delete the inorder successor. Note that inorder predecessor can also be used.

How to delete a node in a BST?
1 Delete node 9 in the following BST : 2 First, we must find the node with the value 9 : (We use the variable p to point to the deletion node ) 3 Next, we find the successor node of the node 9 . 4 We copy the content of the successor node of the node into the deletion node (p) :

How to remove all the half nodes in a binary tree?
The idea is to use post-order traversal to solve this problem efficiently. We first process the left children, then right children, and finally the node itself. So we form the new tree bottom up, starting from the leaves towards the root. By the time we process the current node, both its left and right subtrees were already processed.
How to remove a child node in XML?
