Median Sorted Arrays

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: 2.00000
      Explanation: merged array = [1,2,3] and median is 2.
      

Example 2:

      Input: nums1 = [1,2], nums2 = [3,4]
      Output: 2.50000
      Explanation: merged array = [1,2,3,4] and median is (2 + 3) / 2 = 2.5.
      

Constraints:

• nums1.length == m
• nums2.length == n
• 0 <= m <= 1000
• 0 <= n <= 1000
• 1 <= m + n <= 2000
• -10^6 <= nums1[i], nums2[i] <= 10^6
