Asked In Google and Microsoft - Product of Array Except Self - Stop Using Division ❌

Описание: Most people try to solve this problem using division — and that’s exactly why they fail interviews.

In this video, I explain the Product of Array Except Self problem using the optimised O(n) approach, without division and without unnecessary extra space.

00:00 - Introduction To The Problem
00:55 - Brute Force Approach and what edge cases will it fail
04:34 - Understanding the better approach to handle edge cases with extra space
11:00 - Coding up the better approach step by step
17:48 - Optimising the better solution to best to make it space efficient
21:05 - Coding up the space efficient solution
25:11 - Conclusion

You’ll learn:

❌ Why the division approach breaks (especially with zeros)

✅ The interviewer-approved prefix & suffix technique

⚡ How to solve it efficiently in linear time

🧠 How to explain this solution clearly during interviews

This problem is commonly asked in:

Coding interviews

DSA rounds

LeetCode / competitive programming

If you’re preparing for software engineering interviews or strengthening your data structures & algorithms fundamentals, this explanation will save you time and confusion.
