Solution to TEST in Java

Glup...well, not a nice increase in performance.

Seems pretty nice, thanks a lot.

SPOJ is not accepting my code?

Both solutions mentioned above also give wrong answer!

Why does SPOJ says that this code gives wrong answer? Any one who solved this in SPOJ please help.

i dont really know java..

but what about:

421
42
3

HTH

they say, it will be 1 or 2 digits only. they won't test 421 on the code. so chill

Hello,
does anybody know why my code is not accepted? I get "runtime error (NZEC)". Earlier when I additionally surrounded the code-line "x = eingabe()" with a try-catch block in order to catch a NumberFormatException from the parseInt()-method i even got "time limit exceeded"... On my machine it works correctly. Here is my code:

import java.util.Iterator;
import java.util.LinkedList;
public class Main
{
	public static void main(String[] args)
	{
		int x;
		LinkedList<Integer> l = new LinkedList<Integer>();
		while(true)
		{
			x = eingabe();
			if(x != 42)
			{
				l.add(new Integer(x));
			}
			else
			{
				break;
			}
		}
		for(Iterator<Integer> i = l.iterator();i.hasNext();)
		{
			System.out.println(i.next());
		}
      System.exit(0);
	}
	static int eingabe()
	{
		String s = "";
		try
		{
			s = new java.io.BufferedReader(new java.io.InputStreamReader(System.in)).readLine();
		}
		catch (java.io.IOException e)
		{
		}
		return java.lang.Integer.parseInt(s);
	}	
}

No, the solution is correct, since 420 is an invalid input Read the problem statement.

Why my following code get runtime error (NZEC)?
Help!!!

I'm getting a NZEC error in code..plz check and reply.
import java.util.*;
public class Main {

public static void main(String args[])
{
	Scanner in=new Scanner(System.in);
	System.out.println("enter the numbers: ");

	int n=0;int i=0;
	int arr[]=new int[10];

	while((n=in.nextInt())!=0)
	{arr[i]=n;	
		i++;

	}
	int j=0;
	while(arr[j]!=42)
	{System.out.println(arr[j]);
	j++;

}


}

}

public class Main
{
  public static void main (String[] args) throws java.lang.Exception
  {
     java.io.BufferedReader r = new java.io.BufferedReader (new java.io.InputStreamReader (System.in));
     String s;
     while (!(s=r.readLine()).startsWith("42")) System.out.println(s);
  }
}

I submitted this code and it got accepted... This is not my code though :mrgreen: .... but this code takes any input and print it out as it is.... Then why was it given in the problem that the number should be two digit or one digit integer only...

I made a different code it was taking all input but printing out only those which are integers of one or two digit... I think that is how it should work... But that code was not accepted... it gives wrong output it seems..

Please post the code that you are having difficulty with. (using code tags, see your post that I edited)

The code that you submit does not have to verify that the input follows the specification. The specification determines what sort of input will be given.

You can rest assured that numbers like 122 and 123455730324903242342393276378234123419 and 1.234 will not occur in the input.

Why is my following code getting "wrong answer" in SPOJ.
It is working fine in my IDE.
Please HELP !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

import java.io.*;
public class Main
{
    /**
 *  This class solves problem 1 classical from SPOJ
 *  @author T
 *  @since 6-Sep-2011
 */
public static void main(String[] args) throws IOException
{
	BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
	while(true)
	{
		System.out.println("Input:");
		String s = br.readLine();
		if(s.equals("42"))
			break;
		else
			System.out.println("Output:" + s);
	}

}
}

         System.out.println("Input:");

Everything that you output is considered in the result. This alone will give you wrong answer.

Works.... Thank u so much.

Here's a good description / explanation on how to approach solving this problem Life, Universe, and everything in Java, C++, and C:

Anybody knows why I keep getting a NZEC error when I try to submit?

I run it in my terminal as following
javac meaningoflife3.java
java meaningoflife3 test.txt

I think it might be because of the text file?

import java.io.*;
public class meaningoflife3 {
    public static void main(String[] args) throws IOException {
	// TODO Auto-generated method stub
	
	File inFile = null;
	
	if (0 < args.length) {
		inFile = new File(args[0]);	
		}
	try {
		String num;
		
	BufferedReader read = new BufferedReader(new FileReader(inFile));
	while ((num = read.readLine()) != null ){
		if ( num.equals("42"))
			break;
		else
			System.out.println(num);
		}
	}
	catch (IOException e){
		e.printStackTrace();
		}	
	}
	
	
}

Hope you guys can help me identify my error!
