Скачать или смотреть Leetcode 671 Explained: Find Second Minimum in Binary Tree 🔥

Welcome to this quick and clear explanation of LeetCode 671: Second Minimum Node in a Binary Tree! 🧠🌳

In this video, we break down the logic step-by-step and walk you through two approaches to solve the problem — a brute force method using a set, and a more optimized DFS approach that targets values greater than the root.

🔍 Problem Summary:
Given a special binary tree where the parent node always has the smallest value among its children, the task is to find the second minimum value in the tree — i.e., the smallest value that’s greater than the root.

🛠️ What You'll Learn:

How to approach tree problems logically

Efficient DFS traversal for selective value search

How to handle duplicates and edge cases

✅ Ideal for:

FAANG interview prep

LeetCode beginners to intermediates

Python learners solving tree-based problems
