Java End Of File - HackerRank Solution
Problem :
"In computing, End Of File (commonly abbreviated EOF) is a condition in a computer operating system where no more data can be read from a data source." — (Wikipedia: End-of-file)
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.
Hint: Java's Scanner.hasNext() method is helpful for this problem.
Input Format :-
Read some unknown n lines of input from stdin(System.in) until you reach EOF;
each line of 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 :-
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.
Solution :
