**Objective:** **– **Find the Lowest Common Ancestor of two given nodes in a Binary Search Tree

*What is Lowest Common Ancestor*

*In a given binary tree, The lowest common ancestor of two nodes n1 and n2 will be a node X such that node X will be the lowest node who has n1 and n2 as its descendants.*

**Similar Problem**: Lowest Common Ancestor in a Binary Tree ( Not Binary Search Tree).

**Example**:

Lowest-Common-Ancestor-BST

**Input:** A binary Search Tree and two nodes n1 and n2.

**Appraoch:**

- Start will the root.
- If root>n1 and root>n2 then lowest common ancestor will be in left subtree.
- If root<n1 and root<n2 then lowest common ancestor will be in right subtree.
- If Step 2 and Step 3 is false then we are at the root which is lowest common ancestor, return it.

**Output**:

Recursive-Lowest Common Ancestor of Nodes 5 and 14 is : 10
Iterative-Lowest Common Ancestor of Nodes 5 and 14 is : 10
