Leetcode 865 | Smallest Subtree with all the deepest nodes | Day 9/365

LeetCode Daily Challenge – Day X/365 🎯 865. Smallest Subtree with All the Deepest Nodes | C++ Solution Explained in Fun Way In today’s LeetCode problem, we find the smallest subtree that contains all the deepest nodes in a binary tree. This is a great problem to master Binary Tree traversal + LCA (Lowest Common Ancestor) concepts efficiently! 🚀 What we do in this video: ✔ Find max depth of the tree ✔ Collect deepest nodes implicitly during recursion ✔ Compute LCA of deepest nodes in a single DFS pass ✔ Return the smallest subtree root containing all deepest nodes 📌 Key Takeaways: ✨ We don’t need to store deepest nodes separately ✨ LCA of deepest nodes is the answer subtree root ✨ This solution automatically picks the minimal subtree ⸻ 🎥 If you enjoyed the explanation, consider: 👍 Like | 💬 Comment | 🔔 Subscribe to Fun Coding for daily LeetCode solutions in a fun and smart way! ⸻ #leetcode #dsa #binarytree #lca #deepestnodes #coding #cpp #softwareengineer #fresher #placements #google #googleprep #gatecs #sbipo #interviewprep #optimus #devlife #recursion #dfs #competitiveprogramming
