Unlock the power of efficient data processing with this in-depth tutorial on Prefix Sum and Frequency Arrays!

In this video, we'll dive deep into two fundamental algorithms that every programmer should know:

✅ Prefix Sum (Cumulative Sum Array): Learn how to quickly calculate sums of ranges in an array. This technique is a game-changer for optimizing solutions to many algorithmic problems, reducing time complexity from O(N) to O(1) for range sum queries!
✅ Frequency Array (Counting Array):Discover how to efficiently count the occurrences of elements within a given range or an entire array. Perfect for problems involving character counts, number frequencies, and more!

What you'll learn:
Understand the core concept and intuition behind Prefix Sum and Frequency Arrays.
Step-by-step implementation in C++
Practical examples and use cases where these techniques shine.
How to optimize your code and solve complex problems more efficiently.

Whether you're preparing for coding interviews, competitive programming, or just want to level up your data structure and algorithm skills, this tutorial is for you!
