Today, I successfully solved the Median of Two Sorted Arrays problem on LeetCode using JavaScript and an optimized binary search approach.
The challenge is to find the median of two sorted arrays without simply merging them. The goal is to achieve an efficient time complexity of O(log(min(m, n))), making the solution suitable even for large input arrays.
💡 My Approach:
Apply binary search to the smaller array.
Divide both arrays into two partitions.
Check whether the elements on the left partitions are less than or equal to those on the right.
If the partition is correct, calculate the median based on whether the total number of elements is even or odd.
Adjust the binary search boundaries until the correct partition is found.
For example, given nums1 = [1, 3] and nums2 = [2], the median is 2.0.

This problem helped me strengthen my understanding of binary search, array partitioning, edge cases, and algorithm optimization.
The biggest lesson I learned is that sometimes the most efficient solution comes from finding the right partition rather than processing every element.
Every problem solved is another step toward becoming a better developer. Consistent practice, logical thinking, and learning from challenges are key to improving problem-solving skills. 🔥
