Deletion in Binary Search Trees
Explore the process of deleting nodes in binary search trees by understanding three key scenarios: deleting leaf nodes, parent nodes with one child, and parent nodes with two children. Learn how to adjust pointers and restructure the tree efficiently with step-by-step guidance.
Introduction
In this lesson, we are going to look at the three deletion cases and the steps required to perform deletion in each case.
The three cases are given below:
- Deletion at Leaf Node
- Deletion at Parent Node
- Node has only one child
- Node has two children
Now let’s look at all the case one by one. ...
