Squares of a Sorted Array

Given an array of integers A sorted in non-decreasing order, return an array of the squares of each number, also in sorted non-decreasing order.

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 {
     public int[] sortedSquares(int[] A) {
         int n = A.length;
         int[] result = new int[n];
         int i = , j = n - ;
         for (int p = n - ; p >= ; p--) {
             if (Math.abs(A[i]) > Math.abs(A[j])) {
                 result[p] = A[i] * A[i];
                 i++;
             } else {
                 result[p] = A[j] * A[j];
                 j--;
             }
         }
         return result;
     }
 }
