977. squares of a sorted array

admin 11月 16, 2020 0

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:

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

Example 2:

1 2	Input: [-7,-3,2,3,11] Output: [4,9,9,49,121]

class  {
    public int[] sortedSquares(int[] A) {
        int[] result = new int[A.length];
        for (int i = 0; i < A.length; i++) {
            result[i] = A[i] * A[i];
        }
        Arrays.sort(result);
        return result;
    }
}
