Data Structures and Algorithms with Python | Free DSA with Python Course - DSA in Python - N-Queens Problem | Recursion & Backtracking | Leetcode 51 - Part 80 [Hindi]

🚀 Welcome to Part 80 of Code & Debug’s DSA in Python Course! In this video, we solve the classic N-Queens problem (Leetcode 51) using Recursion & Backtracking. This is one of the most famous constraint satisfaction problems, where we place N queens on an N×N chessboard so that no two queens attack each other. 📚 What you’ll learn in this video: ✅ Understanding the chessboard constraints for N-Queens ✅ Recursive Backtracking strategy to place queens safely ✅ Optimizations using hashing for columns & diagonals ✅ Time and space complexity analysis ✅ Handling edge cases and understanding the recursion tree 💡 Why is this important? The N-Queens problem is a staple in interviews and competitive coding. It builds deep intuition for backtracking, grid-based problems, and safe placement logic—essential for problems involving 2D recursion and constraints. 👉 Link to solve this question: https://leetcode.com/problems/n-queens/description/ 👉 Refer the article below for better understanding: https://codeanddebug.in/blog/n-queens/ 👉 📄 Access the full YouTube DSA Playlist Sheet (All Questions in Order): 🔗 https://docs.google.com/spreadsheets/d/1AWE15Fy3wD2iqu2vjK_R7cCiuvSsjYQclcdZmHpF66o/edit?usp=sharing 👉 Enroll in the free DSA Python course here: https://codeanddebug.in/course/master-dsa-with-leetcode 👉 Enroll for Self-Paced Advance DSA course here: https://codeanddebug.in/course/zero-to-hero-python-dsa 🙏 Thank you for supporting Code & Debug!
