    977 - Squares of a Sorted Array\.

    Easy

    Given an integer array nums sorted in non-decreasing order, return an array of the squares of each number sorted in non-decreasing order.

    Example 1:

    Input: nums = -4,-1,0,3,10

    Output: 0,1,9,16,100

    Explanation: After squaring, the array becomes 16,1,0,9,100. After sorting, it becomes 0,1,9,16,100.

    Example 2:

    Input: nums = -7,-3,2,3,11

    Output: 4,9,9,49,121

    Constraints:

    • <code>1 <= nums.length <= 10<sup>4</sup></code>

    • <code>-10<sup>4</sup><= numsi<= 10<sup>4</sup></code>

    • nums is sorted in non-decreasing order.

    Follow up: Squaring each element and sorting the new array is very trivial, could you find an O(n) solution using a different approach?
