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 <= A.length <= 10000-10000 <= A[i] <= 10000Ais sorted in non-decreasing order.
