WebAug 19, 2024 · Let us consider an example to create a Binary Search Tree. Create a Binary Search Tree using the following values: 15, 10, 4, 12, 35, 90, 25, 30 The steps involved are as follows: First, create a root node ,here it is 15 . Then insert the value 10. 10 is lesser than 15. So it becomes the left child of 15. Now, insert the value 4.
