4. Squares of a Sorted Array

Title：

Given an array of integers A sorted in non-decreasing order, return an array of the squares of each number, also in sorted non-decreasing order.

Example 1:

Input: [-4,-1,0,3,10]
Output: [0,1,9,16,100]

Example 2:

Input: [-7,-3,2,3,11]
Output: [4,9,9,49,121]

Note:

1. 1 <= A.length <= 10000
2. -10000 <= A[i] <= 10000
3. A is sorted in non-decreasing order.

Analysis of Title：

It means to return a Ascending order array.

Test case：

A=[-4,-1,0,3,10]

Python：

return sorted([x*x for i in A])

Analysis of Code：

sorted()  return a Ascending order array.
