LeetCode 977. 有序数组平方的排序 by Python3

class Solution: #等于没做出来，基本上参考的代码随想录的码
    def sortedSquares(self, nums: List[int]) -> List[int]:
        l = len(nums) - 1
        tempNums = [0] * (l + 1)
        start = 0
        end = l
        i = l
        while start <= end:
            s = nums[start] ** 2
            e = nums[end] ** 2
            if s > e:
                tempNums[i] = s
                start += 1
            else:
                tempNums[i] = e
                end -= 1
            i -= 1
        return tempNums

虽然已经想到双指针法了，但是却是从中间往两边对比，把问题复杂化，属于没有领悟列表的双指针法思想。
