Median of Two Sorted Arrays
Given two sorted arrays nums1 and nums2 Return the median of the combined sorted arrays Must use O(log(m+n)) time complexity Example: nums1 = [1,3], nums2 = [2] => 2.0 Example: nums1 = [1,2], nums2 = [3,4] => 2.5
Binary search on the smaller array to find the partition point where left half elements all <= right half elements in both arrays - handle edge cases with infinity. O(log(min(m,n))) and a brutal problem that tests binary search mastery; understanding the invariant is half the battle.
