Which of the following is a correct method to delete a node with one child in a BST?Replace the node with its childReplace the node with the rootReplace the node with its inorder predecessorDelete the subtree containing the node
Solution
The correct method to delete a node with one child in a Binary Search Tree (BST) is to replace the node with its child. Here are the steps:
- Identify the node to be deleted.
- Check if the node has one child.
- If the node has one child, replace the node with its child.
- If the node to be deleted is the left child of its parent, then update the left pointer of the parent to point to the child of the node to be deleted.
- If the node to be deleted is the right child of its parent, then update the right pointer of the parent to point to the child of the node to be deleted.
- Finally, delete the node.
The other options mentioned are not correct methods for deleting a node with one child in a BST.
