Java Strings Introduction

/*
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,  and , perform the following operations:

Sum the lengths of  and .
Determine if  is lexicographically larger than  (i.e.: does  come before  in the dictionary?).
Capitalize the first letter in  and  and print them on a single line, separated by a space.
Input Format

The first line contains a string . The second line contains another string . 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  and .
For the second line, write Yes if  is lexicographically greater than  otherwise print No instead.
For the third line, capitalize the first letter in both  and  and print them on a single line, separated by a space.

Sample Input 0

hello
java
Sample Output 0

9
No
Hello Java
Explanation 0

String  is "hello" and  is "java".

 has a length of , and  has a length of ; the sum of their lengths is .
When sorted alphabetically/lexicographically, "hello" precedes "java"; therefore,  is not greater than  and the answer is No.

When you capitalize the first letter of both  and  and then print them separated by a space, you get "Hello Java".
