[OT] fastest fibbonacci

[Stefam Koch via Digitalmars-d]

Hi Guys,

while brushing up on my C and algorithm skills, accidently 
created a version of fibbonaci which I deem to be faster then the 
other ones floating around.

It's also more concise

the code is :

int computeFib(int n)
{
     int t = 1;
     int result = 0;

     while(n--)
     {
         result = t - result;
         t = t + result;
     }

    return result;
}
