Welcome to Day 04 of our Complete Data Structures & Algorithms (DSA) Roadmap! 💡
Today, we take on our very first Hard-level challenge: LeetCode 04 HARD - Median of Two Sorted Arrays. This classic problem is frequently asked in top-tier FAANG interviews (Google, Amazon, Apple, Microsoft) to test deep understanding of divide-and-conquer and binary search.
We break down the raw intuition step-by-step, explain why merging is too slow, and implement the optimal O(log(min(m, n))) Binary Search Partition approach using Python. 🐍

📌 𝗪𝗛𝗔𝗧 𝗬𝗢𝗨'𝗟𝗟 𝗟𝗘𝗔𝗥𝗡 𝗜𝗡 𝗧𝗛𝗜𝗦 𝗩𝗜𝗗𝗘𝗢:
• Problem Breakdown: Understanding median conditions for even and odd lengths
• Brute-Force vs Optimal: Why merging takes O(m + n) and how to hit O(log(min(m, n)))
• Binary Search on Partitions: Splitting two arrays cleanly into left and right halves
• Handling Edge Cases: Infinity padding for boundary conditions and unequal array sizes
• Clean Python Implementation: Step-by-step raw coding and dry run walkthrough
