Given two sorted arrays nums1 and nums2 of size m and n respectively, return the median of the two sorted arrays.
The overall run time complexity should be O(log(m + n)).
Example 1:
Input: nums1 = [1, 3], nums2 = [2]
Output: 2
Explanation: Merged array = [1, 2, 3] and median is 2.
Example 2:
Input: nums1 = [1, 2], nums2 = [3, 4]
Output: 2.5
Explanation: Merged array = [1, 2, 3, 4] and median is (2 + 3) / 2 = 2.5.
nums1.length == mnums2.length == n0 <= m <= 10000 <= n <= 10001 <= m + n <= 2000-10^6 <= nums1[i], nums2[i] <= 10^6
