The 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.

lines of input from stdin(System.in) until you reach EOF; each line of the input contains a non-empty String.
Output Format
For each line, print the line number, followed by a single
space, and then the line content received as input.
Sample Input

I am a file
Read me until end-of-file.

/* Enter your code here. Read input from STDIN.
Print output to STDOUT. Your class should be named Solution. */
Scanner sc = new Scanner(System.in);
for(int i = 1; sc.hasNext()== true; i++){
System.out.println(i + " " + sc.nextLine());
}
