Solution: Find Minimum Value in Binary Search Tree

Explore how to find the minimum value in a binary search tree by applying iterative and recursive approaches in Python. Understand the algorithm's logic based on BST properties and analyze the time and space complexities for balanced and skewed trees.

Statement

Given the root node of a binary search tree (BST), find and return the minimum value present in the BST.

Constraints:

Let n be the number of nodes in a binary search tree.

  • 00 \leq n 500\leq500

  • 104-10^4\leq Node.data 104\leq10^4

Solution 1: Iterative approach

The essence of the algorithm lies in the property of a BST, where the left subtree of a node contains values smaller than the node's value. Therefore, by traversing always to the left child, the algorithm guarantees that it reaches the minimum value node in the BST. ...
