4. Median of Two Sorted Arrays

There are two sorted arrays nums1 and nums2 of size m and n respectively.

Find the median of the two sorted arrays. The overall run time complexity should be O(log (m+n)).

You may assume nums1 and nums2 cannot be both empty.

Example 1:

nums1 = [1, 3]
nums2 = [2]

The median is 2.0

Example 2:

nums1 = [1, 2]
nums2 = [3, 4]

The median is (2 + 3)/2 = 2.5

        :type nums1: List[int]
        :type nums2: List[int]
        :rtype: float
        """
        for i in nums2:
            nums1.append(i)
        nums1.sort()
        if len(nums1)%2==0:
            return float((nums1[int(len(nums1)/2)]+nums1[int(len(nums1)/2)-1])/2)
        else:
            return float(nums1[int((len(nums1)-1)/2)])
