LeetCode 1009 – Complement of Base 10 Integer | Bit Manipulation Trick Explained (O(logN) Solution)

In this video, we solve LeetCode 1009 – Complement of Base 10 Integer using a clean and efficient Bit Manipulation approach. 💡 Instead of converting to string or manually flipping bits, we build a smart bitmask and compute the complement in O(log N) time. 🔎 What You’ll Learn: What “complement” really means in binary How to construct a bitmask dynamically Why handling leading zeros is important Optimized bit manipulation approach Edge case: when n = 0 🧠 Approach Covered: Convert number to binary (conceptually) Create mask with all 1s of same length XOR number with mask to get complement ⏱ Time Complexity: O(log N) 📦 Space Complexity: O(1) Perfect for: Beginners learning Bit Manipulation Coding Interview Preparation Daily LeetCode Practice FAANG Interview Prep #LeetCode #BitManipulation #CodingInterview #DailyLeetCode #DSA #InterviewPreparation #Binary #Programmer #TechYouTube
