Delete operation in a binary search tree

By | July 15, 2020

In this post, We will learn How to perform delete operation in a binary search tree?

The Delete Operation in BST:

•First of all, We have to find the node we wish to delete (if it is there).
• If we find that the node is a leaf then delete it.
• If we find that the node has exactly one child, delete the node by making its parent refer to that child directly.
• If we find that the node has two children, replace the value in the node by the value in its successor and then after deleting the successor.

Complete Souce code:

Delete value from Binary Search Tree

BinaryTree.java

 

ClientTest.java

The Input/output of This Program:

Original Binary tree…
10 5 15 40 80 60 70

Enter Value which you want to delete:
40
After deleting node with value:40 Binary tree..
10 5 15 60 80 70
