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?
