i'm still waiting for the fix :)

Very simple one. Good!
tip: try using for-loop or lambda :)

hmmm lambda! i see those everwhere, yet they are so mysterious :p

Best Practice :)

OMG!!

That's Awesome!!!!!!!!!!

Should be protected :)

USE -> if (arrayOfSheep != null && arrayOfSheep). cheers

FYI: Use the class (Boolean) not a primitive datatype (boolean) and also check for nulls! - as simple as it is ;)

The test code for Java is utterly wrong!.

is it fixed yet? - apparently not. :( - i'm raising an another issue.

Need more refinement for Java!

Well, I wouldn't say i'm a math-boy but i do intend to fix any problem with algorithms and formulae', not sure how you people are going to react based on my answers!! (fingers crossed) :o

JAVA:
The test case class has incorrect code(compile error)!

replace thetestcase with this code:

import static org.junit.Assert.*;
import org.junit.Test;

public class RobotTest {

@Test
 public void haha() throws Exception
 {
  Robot obj = new Robot();
  assertEquals(obj.reverse("emma"),"amme");
 }

 @Test
 public void hehe()throws Exception
 {
  Robot obj = new Robot();
  assertEquals(obj.reverse("Alphonse"),"esnohplA");
 }

}
