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 a node from an HTML document?
This example uses removeChild () to remove the text node from the first element. This example uses the nodeValue () property to clear the text node of the first element.
How to remove a title node in XML?
Try it Yourself ». Example explained: Suppose ” books.xml ” is loaded into xmlDoc. Set the variable x to be the first title element node. Set the variable y to be the text node to remove. Remove the element node by using the removeChild () method from the parent node.
Is it possible to delete a node without a head pointer?
Conventional deletion is impossible without knowledge of the previous node of a node that needs to be deleted. The trick here is we can copy the data of the next node to the data field of the current node to be deleted. Then we can move one step forward.
How to delete a node with two subtrees?
Deleting a node that has two subtrees is very complicated …. Here is the summary of the procedure : Before we can discuss the deletion algorithm , we must discuss how to find the successor node first …. Deleting a node with 2 subtrees: illustrating the algorithm with examples
How to delete a node from a binary search tree?
Notice that the tree satisfies the Binary Search Tree property: all nodes in the right subtree has larger values . Next, we find the successor node of the node 6 . Because the successor node does not have a left subtree , we can delete the successor node using the short-circuit method (of Case 2 )
How to find the successor node of a node?
Next, we find the successor node of the node 9 . The successor node is the node with the minimum value in the right subtree : Notice that the tree satisfies the Binary Search Tree property: all nodes in the right subtree has larger values . Next, we find the successor node of the node 6 .
