Hello,

I am having trouble with the first question in the Programming Challenges book by Skiena and Revilla. I keep getting a "Wrong Answer" error message, and I don't know why. I've ran my code against the sample input, and I keep getting the right answer. Anyways, if anyone could help me, I would really appreciate it :)

Here is the problem URL: http://uva.onlinejudge.org/index.php?option=com_onlinejudge&Itemid=8&category=29&page=show_problem&problem=36

And here is the code:`

import java.util.Scanner;

public class Main
{
 static Scanner kb = new Scanner(System.in);

 public static void main(String[] args)
 {
  while (kb.hasNext())
  {
   long[] numericalInput = {0, 0};

   long i = kb.nextLong();
   long j = kb.nextLong();

   if (i > j)
   {
    numericalInput[0] = i;
    numericalInput[1] = j;
   }
   else
   {
    numericalInput[0] = j;
    numericalInput[1] = i;
   }

   long maxIterations = 0;

   for (long n = numericalInput[0]; n <= numericalInput[1]; n += 1)
   {
    if (maxIterations < returnIterations(n))
     maxIterations = returnIterations(n);
   }

   System.out.println(i + " " + j + " " + maxIterations);
  }

  System.exit(0);
 }

 public static long returnIterations(long num)
 {
  long iterations = 0;

  while (num != 1)
  {
   if (num % 2 == 0)
    num = num / 2;
   else
    num = 3 * num + 1;

   iterations += 1;
  }
  iterations += 1;

  return iterations;
 }
}

` EDIT: I think the problem is with the output. I tried to make it accept all the input first and then display all the answers at once, but I didn't know the terminating condition. I resorted to this method, but I'm not sure that's what the judge wants...
