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)).
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
def main(nums1,nums2): nums1.extend(nums2) nums1.sort() len1=len(nums1) if len1: if len1%2==0: return (nums1[len1//2]+nums1[len1//2-1])/2 else: return nums1[len1//2] # print(l1) if __name__ == '__main__': l1=[1,3] l2=[2] print(main(l1,l2))
