LeetCode 100 | Same Tree | Recursion Explained Step-by-Step | C++ Solution 🔥

In this video, we solve LeetCode 100 – Same Tree using a clean and efficient recursive approach in C++.

This is a fundamental binary tree problem where we compare two trees to check whether they are identical in both structure and node values.

🔍 What you will learn:
- How to compare two binary trees
- Recursive approach explained clearly
- Base cases in tree recursion
- Step-by-step code explanation
- Time and space complexity analysis

🧠 Approach:
We compare both trees node by node:
- If both nodes are NULL → return true
- If one is NULL → return false
- If values differ → return false
- Recursively check left and right subtrees
