Solution: Find Minimum Value in Binary Search Tree

Explore how to find the minimum value in a binary search tree by traversing the left subtree. Understand both iterative and recursive methods with clear steps. This lesson also covers time and space complexity analysis to help you implement efficient tree algorithms in Go.

We'll cover the following...

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.

  • 0≤0 \leq n ≤500\leq500

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