# 0977. Squares of a Sorted Array

https://leetcode.com/problems/squares-of-a-sorted-array

## Description

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:**

* `1 <= nums.length <= 104`
* `-104 <= nums[i] <= 104`
* `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?
