Sum of Deepest Level Nodes in a Binary Tree | Easy DFS & BFS Explanation (LeetCode)

In this video, we solve the Sum of Deepest Level Nodes in a Binary Tree problem step by step.
The goal is to find the sum of all node values present at the deepest level of a binary tree.

We’ll break down the problem with:

A clear explanation of what the deepest level means

Visual intuition using tree traversal

Two clean approaches: DFS (Depth First Search) and BFS (Level Order Traversal)

Time and space complexity analysis

This problem is perfect for strengthening your understanding of binary tree depth, recursion, and level-based traversal, which are frequently asked in coding interviews.

📌 Topics Covered
✔ Binary Trees
✔ DFS vs BFS
✔ Tree Depth
✔ Interview-friendly approach

If you’re preparing for LeetCode, FAANG interviews, or coding rounds, this tutorial will help you think clearly and write clean solutions.
