Input Format

The first line contains a single string denoting 8.
The second line contains two space-separated integers denoting the respective values of start and end .


  • String  consists of English alphabetic letters (i.e., ) only.

        /* Save input */
        Scanner scan = new Scanner(;
        String A =;
        String B =;
        /* Sum lengths */
        System.out.println(A.length() + B.length());
        /* Compare lexicographical ordering */
        System.out.println(A.compareTo(B) > 0 ? "Yes" : "No");
        /* Print the Strings in desired format */
        System.out.println(capFirstLetter(A) + " " + capFirstLetter(B));
    private static String capFirstLetter(String str) {
        if (str == null || str.length() == 0) {
            return "";
        } else {
            return str.substring(0,1).toUpperCase() + str.substring(1);
