Those days..

Today was the birthday of Ragnarok, it was really funny and we joke and talk for about six hours =S.

I was testing colorize in the gimp and I will release some manipulated images in deviantart.com, the images I have released are:

• Spin Top


• Those days

I also found a new radio station, really cool, except it repeats much of his music =( Virgin Radio UK, yesterday I was listening 'Late Show with Leona' which started about 10 pm... in England, 3 pm in Mexico =P.

Checking my mail I found a Top Coder problem about 'masive numbers', which was really simple, my solution (trying to be more legible than the original answer, which I found later) is:

------
MassiveNumbers.java
------

public class MassiveNumbers 
{
 public static String getLargest(String numberA, String numberB)
 {
  String m, n;
  double a, b;
  double c, d;
  double result;
  
  int index_m, index_n;
  
  m = numberA.trim();
  n = numberB.trim();
  
  index_m = m.indexOf("^");
  index_n = n.indexOf("^");
  
  if (index_m == -1 || index_n == -1)
   return null;
  
  try
  {
   a = (new Double(m.substring(0, index_m))).doubleValue();
   c = (new Double(n.substring(0, index_n))).doubleValue();
   
   b = (new Double(m.substring(index_m + 1))).doubleValue();
   d = (new Double(n.substring(index_n + 1))).doubleValue();
  }
  catch(Exception e)
  {
   return null;
  }
  
  result = (d * Math.log(c)) - (b * Math.log(a));
  
  if (result > 0) //c^d > a^b ie n > m
   return numberB;
  else
   return numberA;
 }
}



---------
test.java
---------

public class test 
{
 public static void main(String[] args)
 {
  String greatest;
  
  if (args.length != 2)
  {
   System.out.println("Uso: test numeroA numberB");
   System.exit(1);
  }
  
  greatest = MassiveNumbers.getLargest(args[0], args[1]);
  
  System.out.println("El numero mayor es: " + greatest);
 }
}
