cool, i suggest you do advance reading. so you can learn the basic structures and rules in java programming, we can't really rely much on our instructors cuz they dont care much about the important...

I've debug it :) check those comments for the correction of your codes..


import java.io.*;
public class Input
{
// public static InputStreamReader reader=new InputStreamReader(System.in);...

^
lol, i guess it's too late...

inputs need to be in a try..catch,

format:
try {
statement
}
catch(Exception ex) {
statement
}
