Insert operation in a binary search tree

By | July 15, 2020

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

The insert method:

We insert an element at the place where we ‘fall off’ the tree looking for it.
To insert key into Tree t:
• If t is empty, replace t by a tree consisting of a single node with value key.
• If t has key at its root, key is already in t. Return without modifying t.
• If key is less than the value at the root of t, insert key into the left subtree
of t.
• If key is greater than the value at the root of t, insert key into the right
subtree of t.

Inserting a node requires a change to its parent. In our recursion logic, we have to pass information back to the parent so it can change itself.
