he challenge here is to read n lines of input until you reach EOF, then number and print all n lines of content. Hint: Java's Scanner.hasNext() method is helpful for this problem.

CSZONE Sample Input Hello world I am a file Read me until end-of-file. Sample Output 1 Hello world 2 I am a file 3 Read me until end-of-file. import java.io.*; import java.util.*; import java.text.*; import java.math.*; import java.util.regex.*; public class Solution { public static void main(String[] args) { /* Enter your code here. Read input from STDIN. Print output to STDOUT. Your class should be named Solution. */ Scanner scan = new Scanner(System.in); int i=1; while(scan.hasNext()){ System.out.println(i + " " + scan.nextLine()); i++; } } }
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 print them on a single line, separated by a space.
