Product of Array Except Self | Brute Force to Optimized Approach | Prefix & Suffix Trick | C++,Java
In this video, we solve the classic interview problem Product of Array Except Self and understand how to move from a simple brute force approach to an optimized solution.
We start with the naive approach where we calculate the product for each element by iterating through the entire array. Then we improve it using the Prefix and Suffix product technique, which helps us achieve O(n) time complexity without using division.
This question is frequently asked in coding interviews at top companies and is a great way to understand prefix computation patterns.
In this video you will learn:
• Brute force approach and its time complexity
• Why brute force is inefficient
• Optimized prefix and suffix product approach
• How to solve it in C++, Java, and Python
• Interview intuition and edge cases
Perfect for DSA interview preparation and strengthening your understanding of array patterns.
