Arrays

Squares of a Sorted Array:

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]


class Solution:
    def sortedSquares(self, nums: List[int]) -> List[int]:
        min_ptr=0
        max_ptr=len(nums)-1
        arr=[0]*len(nums)
        i=len(nums)-1
        while min_ptr<=max_ptr:
            if abs(nums[min_ptr])<abs(nums[max_ptr]):
                arr[i]=nums[max_ptr]*nums[max_ptr]
                i-=1
                max_ptr-=1
            else: 
                arr[i]=nums[min_ptr]*nums[min_ptr]
                min_ptr+=1
                i-=1
               
        return arr
