Why WA#12??????
This my code:

import java.util.Scanner;
public class T_1433 {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        String s_1 = sc.next();

        String left = s_1.substring(1,2);// tetraedr chap tamoni
        String right = s_1.substring(2,3);// tetraedr o'ng tamoni
        String back = s_1.substring(3,4);//  tetraedr orqa tamoni
        String s_2 = sc.next(); // 2-tetraedr...
        boolean equal = false;
        //--------------------------
        if(asos.equals(s_2.substring(0,1))){
