Hi this is the code i submitted and it passed all test cases, but i am confused as to why this line worked (A.compareTo(B) > 1). When i used the line A.compareTo(B) == 1 test case two kept on failing until i made this change by mistake i meant to write 0 (zero) instead of 1 (one).

import java.io.; import java.util.;

public class Solution {

public static void main(String[] args) {

    Scanner sc=new Scanner(System.in);
    String A=sc.next();
    String B=sc.next();
    sc.close();

    System.out.println(A.length() + B.length());

    if(A.compareToIgnoreCase(B) > 1)
            System.out.println("Yes");
        else
            System.out.println("No");

    System.out.println(
        A.replace(A.charAt(0), Character.toUpperCase(A.charAt(0)))
        +" "+ B.replace(B.charAt(0), Character.toUpperCase(B.charAt(0))));

}

}
