🔥Leetcode 22 | Generate Parenthesis | Backtracking | POTD | #dsa #potd #leetcode #telugu

📌 *Problem:* Generate Parentheses – LeetCode 22 🔗 *Problem:* https://leetcode.com/problems/generat... 💻 *Solution:* https://leetcode.com/problems/generat... In this video, we solve *Generate Parentheses* using an **optimal Backtracking approach**. This is a classic recursion and backtracking problem and an important pattern for coding interviews. 🧠 *Key Idea:* Build the parentheses string step by step using recursion. We can add an opening parenthesis while we still have some left, and add a closing parenthesis only when it keeps the sequence valid. 📚 *Concepts Covered:* Recursion Backtracking Parentheses String Construction Constraint-Based Generation Decision Tree ⏱️ *Time Complexity:* O(4ⁿ / √n) 💾 *Space Complexity:* O(n) This problem is part of my **DSA Playlist**, where I explain important DSA patterns and frequently asked interview problems step by step in Telugu. #LeetCode #LeetCode22 #GenerateParentheses #Backtracking #Recursion #Stack #DSA #DSAPlaylist #DSAinTelugu #Telugu #Python #CPlusPlus #Java #CodingInterview #InterviewPreparation
