Read a set of numbers and group them by their remainder when dividing to 3 (0, 1 and 2). One first line, you will get numbers separated with coma.

Гърми ми на 4 тест и не мога да разбера защо. Кода ми е това:

import java.util.Scanner;

public class groupNums04 {
    public static void main(String[] args){
        Scanner input = new Scanner(System.in);

        String space = " ";

        String rem0 = new String();
        String rem1 = new String();
        String rem2 = new String();

        String[] lineNums = input.nextLine().split(", ");
        int[] lineNumsArr = new int[lineNums.length];

        for (int i =0; i < lineNumsArr.length; i ++){
            lineNumsArr[i] = Integer.parseInt(lineNums[i]);
        }

        for(int i =0; i < lineNumsArr.length; i ++){
            int remainder = Math.abs(lineNumsArr[i]) %3;
            if (remainder == 0){
                rem0 = rem0 + " " + Integer.toString(lineNumsArr[i]);

            } else if (remainder == 1){
                rem1 = rem1 + " " + Integer.toString(lineNumsArr[i]);

            } else if (remainder == 2){
                rem2 = rem2 + " " + Integer.toString(lineNumsArr[i]);
                
            }
        }

        String[] allRemainders = new String[]{rem0.trim(), rem1.trim(), rem2.trim()};

        int[][] jagged = new int[3][];

        for (int i = 0; i < jagged.length; i ++){
            String[] inputNums = allRemainders[i].split(" ");
            jagged[i] = new int[inputNums.length];

            for (int j = 0; j < inputNums.length; j ++){
                jagged[i][j] = Integer.parseInt(inputNums[j]);
            }
        }

        for (int i =0; i < jagged.length; i ++){
            for (int j = 0; j < jagged[i].length; j++){
                System.out.printf("%d ", jagged[i][j]);
            }
            System.out.println();
        }
    }
}
