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)).
example：
nums1 = [1, 3] nums2 = [2]
The median is 2.0
简单来说，这道题的要求就是求两个数组的中位数，因为最近一直在学习Python，所以给大家展现下我自己的想法，希望大家互相交流。
class Solution:
def findMedianSortedArrays(self, nums1, nums2):
#连接两个数组
nums3 = nums1 + nums2
#数组排序
nums3.sort()
#初始化中位数的值为0
med = 0
index = index1 = index2 = 0
lenofnums = len(nums3)
if((lenofnums % 2) == 0):
#如果为偶数个则取中间两个数的平均值
index1 = int(lenofnums / 2 - 1)
index2 = int(index1 + 1)
med = (nums3[index1] + nums3[index2]) / 2
else:
#如果为奇数个直接取中间值
index = int((lenofnums + 1) / 2 - 1)
med = nums3[index]
return med
