"A string is traditionally a sequence of characters, either as a literal constant or as some kind of variable." — Wikipedia: String (computer science)
This exercise is to test your understanding of Java Strings. A sample String declaration:
String myString = "Hello World!"
The elements of a String are called characters. The number of characters in a String is called the length, and it can be retrieved with the String.length() method.
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 nd print them on a single line, separated by a space.
Input Format
The first line contains a string A. The second line contains another string B. The strings are comprised of only lowercase English letters.
Output Format
There are three lines of output:
For the first line, sum the lengths of A and B.
For the second line, write Yes if A is lexicographically greater than B otherwise print No instead.
For the third line, capitalize the first letter in both A and B and print them on a single line, separated by a space.

import java.util.Scanner;
public class Solution{

Scanner input = new Scanner(System.in);
String a = input.next();
String b = input.next();
System.out.println(a.length() + b.length());
System.out.println(a.compareTo(b) > 0? "Yes" : "No");
System.out.println(a.substring(0,1).toUpperCase() + a.substring(1, a.length()) + " " + b.substring(0,1).toUpperCase() + b.substring(1, b.length()) );
}
