1. 思路：先平方，再冒泡排序，结果
   

class Solution(object):
    def sortedSquares(self, nums):
        """
        :type nums: List[int]
        :rtype: List[int]
        """
        c = []
        for i in nums:
            c.append(i*i)
        def bubbleSort(arr):
            for i in range(1,len(arr)):
                for j in range(0,len(arr)-i):
                    if arr[j]>arr[j+1]:
                        arr[j],arr[j+1] = arr[j+1],arr[j]
            return arr
        return(bubbleSort(c))
