Welcome to srkcodes! In this Day 108 Telugu coding tutorial, we solve Leetcode Q378 - Kth Smallest Element in a Sorted Matrix, an important DSA interview question that checks your skills in matrix traversal, heaps, and sorting.

If you're preparing for Python programming interviews, this video will guide you through two different approaches to solve this problem efficiently — both brute-force and optimal!

🔍 What You’ll Learn in This Video:
Understanding the matrix structure and the problem constraints
Brute-force Approach using array flattening + sorting
Optimal Min-Heap Approach using priority queues (heapq)
How to handle sorted matrices in DSA problems
Memory-optimized techniques & time complexity analysis

💡 Key Takeaways:
Master the logic behind matrix-based DSA interview questions
Learn Min-Heap implementation in Python using heapq
Compare brute-force vs optimal methods with complexity breakdown
Get hands-on with Python programming for interviews
Strengthen your tech career prep with advanced problem solving

💬 Practice Challenge:
Try solving this with Binary Search on value range (most optimal). Drop your logic in the comments!
