Binary Search Tree Insertion

Learn about the binary search tree insertion algorithm!

We'll cover the following

Binary Search Tree Insertion Algorithm

Here is a description of the algorithm used to insert a new value into a BST:

  1. Start from the root node.

  2. Check if the value to be inserted is greater than the root/current node’s value

  3. If yes, then repeat the steps above for the right-subtree. Otherwise, repeat the steps above for the left-subtree of the current node.

  4. Repeat until you find a node that does not have a right/left child to move onto. Insert the given value there, and update the parent node accordingly.
