Median of Two Sorted Arrays | LeetCode #4 Hard | Binary Search Solution | Asked in Amazon, Google
🚀 Median of Two Sorted Arrays | LeetCode #4 Hard | Optimal Binary Search | Amazon, Google | Java & Python
In this video, we solve one of the most challenging LeetCode problems - "Median of Two Sorted Arrays" with the optimal O(log(min(m,n))) approach using Binary Search. This hard-level problem is frequently asked in FAANG companies (Amazon, Google, Microsoft, Meta, Apple) and top product-based companies.
🔑 What You'll Learn:
✅ Problem statement explained with real-world examples
✅ Why brute force O(m+n) is not enough for interviews
✅ Key Observation: Partitioning two sorted arrays correctly
✅ Binary Search approach on the smaller array
✅ How to find median using left and right partitions
✅ Edge cases: odd/even total length, empty arrays
✅ Step-by-Step Pseudocode + Algorithm Design
✅ Full Coding Implementation in Java & Python on LeetCode
✅ Time Complexity O(log(min(m,n))) & Space Complexity O(1)
✅ Interview Tips: How to explain this hard problem clearly
