Leetcode - 004 - Median of Two Sorted Arrays

4. Median of Two Sorted Arrays

Hard

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
    -106 <= nums1[i], nums2[i] <= 106
