Data Structures and Algorithms with Python | Free DSA with Python Course - DSA in Python - Single Number | Bit Manipulation & XOR Trick | Leetcode 136 - Part 67 [Hindi]

🚀 Welcome to Part 67 of Code & Debug’s DSA in Python Course! In this lecture, we solve Leetcode Problem 136: Single Number, a classic problem that uses Bit Manipulation (XOR trick) to find the unique element in an array where every other number appears twice. 📚 What you’ll learn in this video: ✅ Understanding the problem statement & constraints ✅ Brute force vs. optimized bitwise XOR approach ✅ How XOR cancels out duplicate elements efficiently ✅ Step-by-step Python implementation ✅ Time and space complexity analysis 💡 Why is this important? The XOR operation is a powerful technique in bitwise programming that helps in finding unique elements, swapping numbers, and detecting differences. This problem is a common interview question and a must-know trick for coding competitions. 👉 Link to solve this question: https://leetcode.com/problems/single-number/description/ 👉 Refer the article below for better understanding: https://codeanddebug.in/blog/single-number/ 👉 📄 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!
