Leetcode-Easy 977. Squares of a Sorted Array

Example 1:

Input: [-4,-1,0,3,10]
Output: [0,1,9,16,100]
Example 2:

Input: [-7,-3,2,3,11]
Output: [4,9,9,49,121]

class Solution:
    def sortedSquares(self, A: 'List[int]') -> 'List[int]':
        return sorted([x**2 for x in A])

class Solution:
    def sortedSquares(self, A):
        answer = [0] * len(A)
        l, r = 0, len(A) - 1
        while l <= r:
            left, right = abs(A[l]), abs(A[r])
            if left > right:
                answer[r - l] = left * left
                l += 1
            else:
                answer[r - l] = right * right
                r -= 1
        return answer
