> The GFCross UDF contains the following code:
> {code}
> int[] digits = new int[numInputs];
> for (int i=0; i<numInputs; i++){
> if (i == myNumber){
> digits[i] = r.nextInt(numGroupsPerInput);
> }else{
> digits[i] = 0;
> }
> }
> {code}
> As int arrays are initialized with all 0s already, this is equivalent to just
> settings digits[myNumber] and leaving the rest alone.
