Day 46 | Clone Graph | LeetCode 133 | JavaScript | DFS + HashMap Deep Copy

🔥 Day 46 of my LeetCode Daily Challenge! Today we solve LeetCode #133 — Clone Graph, a classic Graph problem where we deep copy an entire undirected graph using JavaScript! ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📌 PROBLEM: Clone Graph 🔗 https://leetcode.com/problems/clone-g... 📊 Difficulty: Medium 🗂️ Topics: Hash Map, Depth-First Search, Graph ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 💡 WHAT YOU'LL LEARN: ✅ How to deep copy / clone a graph in JavaScript ✅ Using a HashMap to track already-visited/cloned nodes ✅ Avoiding infinite loops caused by cycles in undirected graphs ✅ DFS approach to graph cloning ✅ Time & Space Complexity Analysis ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🧠 APPROACH: → Use a HashMap (Map) to store original node → cloned node mapping → For each unvisited node, create a new clone node → Recursively clone all neighbors → The HashMap prevents re-cloning already visited nodes (handles cycles!) → Time Complexity: O(V + E) | Space Complexity: O(V) (V = vertices/nodes, E = edges) ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📚 MY LEETCODE JOURNEY PLAYLIST:    • Leetcode   🤝 CONNECT WITH ME: • GitHub: https://github.com/ashwinikemshetty • LinkedIn:   / ashwinikemshetty   📅 #100DaysOfCode #LeetCodeChallenge 🌟 If this helped you, LIKE 👍, COMMENT 💬 & SUBSCRIBE 🔔! ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ #LeetCode #JavaScript #DSA #Day46 #CloneGraph #LeetCode133 #CodingChallenge #ProblemSolving #BFS #DFS #GraphTraversal #100DaysOfCode #JavaScriptDeveloper #DataStructures #Algorithms #TechInterview #CodingInterview #DeepCopy #HashMap #GraphProblems
