Hey guys. I have been trying to write a progamme, and for some reason it doesn't give me the result I want. Anyway, here is a description of the programme I want:

"Suppose that a is a positive integer. Suppose we repeatedly modify a as follows: if a is even, we

divide it by 2, if a is odd, we multiply it by 3 and add 1; we stop the process when a is equal to

1. Write the method lengthSeq(a) that returns the number of values assigned to a.

For example lengthSeq(5) should return the value 6 (sequence: 5 16 8 4 2 1), lengthSeq(13)

should return the value 10 (sequence: 13 40 20 10 5 16 8 4 2 1), and lengthSeq(1) should return

the value 1. Write a method that given a value a returns lengthSeq(a)."

Ok, so my programme prints out 2 for all/most values of int a for some reason. I have the feeling that my mistake is painfully obvious (or at least i hope so, otherwise i'd probably have to rewrite the whole thing) could you help me find what is wrong?

```
public class Question3
{
public static void main (String arg [])
{
int a = 13;
{
int count = lengthSeq (a);
System.out.println (count);
}
}
public static int lengthSeq (int a)
{
int count = 0;
while (a != 1)
{
if (a%2 == 0)
a = (a/2);
count++;
if (a%2 != 0)
a = ((3*a) + 1);
count++;
if (a == 1)
count++;
break;
}
a = count;
return a;
}
}
```
