Course Description Video :

please watch this video at 1.25x for better experience.

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].

Brute force approach also O(N) time complexity only right? O(N) +O(N) = O(2N) =O(N) Correct me if I am wrong

nagalakshmikesavan

what is the space complexity for this program - O(N) ?
can we optimize and make it to O(1) ?
