It said whitespace differs but I cannot solve it.

1 test passed 1 import java.util.Scanner; 2 public class Output Combinations { public static void main(String[] args) { 4 Scanner scnr = new Scanner(System.in); 5 char a; 6 char b; 7 char c; All tests passed 9 10 11 12 13 14 15 16 17 18 19} a = scnr.next().charAt(0); b = scnr.next().charAt(0); C = scnr.next().charAt(0); a = 'x'; b = 'y'; c = 'z'; System.out.println("" +a + b + C +""+ a + C + + "" + b + a + C +""+ b + C + a +""+ C + a + b+ " " + C + b + a); System.out.println(""); } Run x Testing with 'x', y', '2' Output is nearly correct; but whitespace differs. See highlights below. Special character legend xyz xzy yxz yzx zxy zyx Your output Expected output xyz xzy yxz yzx zxy zyx
