๐Ÿ“ฐ Dev.to ยท Rajguru Yadav

Learn to delete a node from a Binary Search Tree in O(h) time without recursion, a rare and challenging coding problem

advanced Published 11 Jul 2025
Action Steps
  1. Understand the properties of a Binary Search Tree (BST) and how node deletion affects it
  2. Identify the different cases for node deletion, such as deleting a leaf node, a node with one child, and a node with two children
  3. Implement an iterative solution to delete a node from the BST in O(h) time
  4. Test the solution with various test cases to ensure its correctness
  5. Compare the iterative solution with a recursive solution to understand the trade-offs
Who Needs to Know This

This problem is relevant to software engineers and developers who work with data structures and algorithms, particularly those who need to optimize their code for efficiency
