def median_of_two_sorted_arrays(nums1, nums2):
    merged = []
    i = j = 0
    while i < len(nums1) and j < len(nums2):
        if nums1[i] <= nums2[j]:
            merged.append(nums1[i])
            i += 1
        else:
            merged.append(nums2[j])
            j += 1
    merged.extend(nums1[i:])
