LeetCode 865 | Smallest Subtree with All the Deepest Nodes | BFS Explained

In this video, we solve LeetCode Problem 865 – Smallest Subtree with All the Deepest Nodes using BFS. We compute the depth of left and right subtrees, compare them, and return the node that contains all deepest nodes in the smallest subtree. ⏱️ Time Complexity: O(n) 📦 Space Complexity: O(n) Perfect for Binary Tree depth-based interview problems. #LeetCode #LeetCode865 #BinaryTree #BFS #TreeProblems #LevelOrderTraversal #DSA #CodingInterview #InterviewPrep #ProblemSolving #LeetCodeDaily #Algorithms #DataStructures
