Solution: Find Minimum Value in Binary Search Tree

Explore how to find the minimum value in a binary search tree using two methods: iterative and recursive. Learn to traverse the BST efficiently by following the left children and analyze the time and space complexity of each solution to enhance your understanding of tree algorithms in C++.

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. ...
