Counting Subarrays with Odd Sum - Detailed Explanation🔥 | Coding Interview Problem ✅

Hey coders! 👋 In this video, we tackle a super common and interesting coding interview problem: "Counting subarrays in an array whose sum is odd." If you've ever struggled with array manipulation or optimizing your solutions, this video is for you!

We'll walk you through a clear, step-by-step explanation of how to efficiently count all the subarrays within a given array that have an odd sum. Forget complex algorithms – we'll show you a surprisingly simple yet powerful approach that you can apply to similar problems.

**What you'll learn in this video:**
* Understanding the properties of odd and even sums.
* A clever trick to optimize your subarray counting.
* The logic behind effectively determining odd sum subarrays.
* Walkthrough with examples to solidify your understanding.
* (Optional: Mention a specific programming language, e.g., "Python implementation will be demonstrated.")

This problem is a fantastic way to sharpen your problem-solving skills and prepare for technical interviews. Don't just copy-paste solutions; understand the *why* behind them!

**Topics Covered:**
* Array Traversal
* Subarray Problems
* Odd/Even Number Properties
* Algorithm Explanation
* Time Complexity Optimization
