HackerRank Java- Strings Introduction
Given two strings of lowercase English letters, A and B, perform the following operations:
Sum the lengths of A and B.
Determine if A is lexicographically larger than B (i.e.: does B come before A in the dictionary?).
Capitalize the first letter in A and B and print them on a single line, separated by a space.
- import java.io.*;
- import java.util.Scanner;
-
- public class Solution {
- public static void main(String[] args) {
- /* Save input */
- Scanner scan = new Scanner(System.in);
- String A = scan.next();
- String B = scan.next();
- scan.close();
-
- /* 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);
- }
- }
