Answer:

The answer is 2. In-order successor

Answer 2

Answer:

If a node having two children is to be deleted from binary search tree, it is replaced by its 3. In-order successor

Step-by-step explanation:

What is binary search tree:

• The Binary Search Tree data structure is a node-based binary tree with the following properties:

1. Only nodes with keys lower than the node's key are found in the left subtree of a node.
2. Only nodes with keys bigger than the node's key are found in the right subtree of a node.
3. Each subtree on the left and right must be a binary search tree.

What is In-order successor:

• In a Binary Search Tree, an input node's Inorder Successor can also be defined as the node with the least key greater than the input node's key.
• As a result, it's occasionally necessary to locate the next node in sorted order.
