Trees Part 3 | Traversals, LCA & Subtree Problems | Master DSA from Scratch

Confused about tree traversals or how recursion and BFS actually work together?
Not sure how problems like LCA or subtree checking are solved cleanly in interviews?

This session builds on earlier tree concepts and focuses on classic, high-frequency interview questions. The goal is to strengthen traversal logic, understand problem patterns, and write clean recursive and level-order solutions.

🔥 What you’ll learn in this session:

✅ Binary Tree Level Order Traversal using BFS
✅ How queue-based traversal works step by step
✅ Subtree of Another Tree explained with recursion
✅ How to compare trees efficiently
✅ Lowest Common Ancestor in a Binary Search Tree
✅ Using BST properties to optimize solutions
✅ Common mistakes in traversal and recursion problems

🎯 Perfect for:

Students who know basic tree concepts
Placement and internship preparation
Anyone wanting to get confident with tree problems
