Standard arrow, kropki, and disjoint group sudoku rules apply. That is:
1) Normal Sudoku rules apply.
2) Digits along an ARROW must sum to the digit in the associated circle
3) DISJOINT GROUP rules apply. Digits in the same position in a box must be different. For example, r1c1 and r4c7 both occupy the top-left position in a box, and therefore must be different.
4) Cells with a white dot between them must be CONSECUTIVE. NOT all possible dots are given (there is NO negative constraint)

Solution code: Row 6 + Row 8 (18 Digits)
