PythonCoincidence，Random algorithmO(nlogn)Push

Course：

1. 看了官方answer，Similar to my first approach，AllsortedLater in the new listappend。But I think I can’t prove the correctness，Because it is Zhou Sai dare not submit at will。
2. Discover when thinking about the first solution，If I keepfor i in Whole array，Determine whether to meet the conditions and then exchange the position，What should I do if I enter the dead cycle?？If a special case fails every time, it needs to be exchanged. What is the difference between random disruption?？
3. After watching the solution of other big guys，I am still too young

   def rearrangeArray(self, nums: List[int]) -> List[int]:
       i = 1
       while i < len(nums)-1:
           if nums[i] == (nums[i - 1] + nums[i + 1]) // 2:
               random.shuffle(nums)
               i = 1
           else:
               i += 1
       else:
           return nums
