Product of Array Except Self: Brute Force to Optimal (No Extra Space) | Module 1

Welcome back to Module 1 of the Ultimate Array Masterclass! 🚀 In this video, we are tackling one of the most famous and high-frequency interview problems: "Product of Array Except Self" (LeetCode 238). We won't just look at the direct solution. We will break it down step-by-step from the Brute Force approach to the optimized Prefix & Suffix product approach using extra space, and finally crack the ultimate interview follow-up: Solving it in O(1) Extra Space! 💡 Key Topics Discussed: • Product of Array Except Self (Brute Force Approach) • Optimized Solution using Prefix and Suffix Arrays (O(N) Time & O(N) Space) • Cracking the LeetCode Follow-Up: O(1) Space Optimization (Without Extra Space) • Handling Edge Cases (Like arrays containing Single or Multiple Zeroes) This problem is a favorite of interviewers at Google, Meta, and Amazon. Mastering this space optimization trick will significantly boost your array problem-solving skills! 💻 Practice Sheets & Material: Make sure to follow along with our full Masterclass Syllabus tracker to monitor your progress, solve practice links, and review revision notes across all modules! 🔥 Don't forget to Like, Subscribe, and hit the Bell Icon to get notified as soon as the next video drops!
