√ Java Strings Introduction- Hacker Rank Solution

Java Strings Introduction- Hacker Rank Solution

Thursday, 24 September 2020

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 come before in the dictionary?).

Capitalize the first letter in A and B and 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.

Sample Input 0

hello

java

Sample Output 0

Hello Java
