I'm solving Uva's 3n+1 problem and I don't get why the judge is rejecting my answer. The time limit hasn't been exceeded and the all test cases I've tried have run correctly so far. 

```
   import java.io.*;

public class NewClass{

    /**
     * @param args the command line arguments

    public static void main(String[] args) throws IOException {

        int maxCounter= 0; 
        int input; 

        int lowerBound; 
        int upperBound; 
        int counter;
        int numberOfCycles;
        int maxCycles= 0;
        int lowerInt;
        BufferedReader consoleInput = new BufferedReader(new InputStreamReader(System.in));
        String line = consoleInput.readLine();
        String [] splitted =  line.split(" ");

        lowerBound = Integer.parseInt(splitted[0]);
        upperBound = Integer.parseInt(splitted[1]);

        int [] recentlyused =  new int[1000001];

if (lowerBound > upperBound )
{
    int h = upperBound;
    upperBound = lowerBound;
    lowerBound = h;

}
lowerInt = lowerBound;
        while (lowerBound <= upperBound)
        {
            counter = lowerBound;
            numberOfCycles = 0;

            if (recentlyused[counter] == 0)

                            counter = 3*counter + 1;
                            }

        System.out.println(lowerInt +" "+ upperBound+ " "+ (maxCycles+1));

    }
