Enormous Input Test Issues

[prankster]

Hi all,
Need some help with this problem, I submitted two different solutions using different i/o techniques

import java.io.*;
import java.util.*;
public class Main
{
	public static void main (String [] args) throws IOException
	{
    BufferedReader input = new BufferedReader (new InputStreamReader (System.in));

String n = input.readLine();

StringTokenizer tok = new StringTokenizer(n," \n");
int n1 = Integer.parseInt(tok.nextToken());
int n2 = Integer.parseInt(tok.nextToken());
int ans = 0;

int count = 0;
while(count <n1)
{

String t = input.readLine();
int t1 = Integer.parseInt(t);

if(t1 % n2 == 0)
ans++;
count ++;
}

System.out.println(ans);
input.close();

}
}

Im getting a "runtime error (NZEC)", can anybody suggest advise. The other solution used the Scanner Class instead of Java IO, and that time I obtained "time limit exceeded" - Note the reason for using the StringTokenizer is to be able to read the two seperate numbers "n" and "k" due to the "readLine()", with the Scanner Class i simply used ".nextInt()" and hence there was no need for a StringTokenizer. Is the Scanner Class slow?

Thanks

Without looking more closely at your code, I'm not sure why you're getting RTE except maybe that there could be spaces before or after the numbers you're reading in, causing parseInt to throw an exception.

Java's Scanner class is very slow because it does a great deal of error handling (good for real-life programming, less so for contest programming). I've written a much more efficient Parser class for Java, which can be found here. viewtopic.php?f=43&t=4864
