Rules:
Normal Sudoku rules apply.
159: Digits in column 1 indicate the column in which the digit 1 appears in that row (e.g. if r4c1 is a 6, r4c6 is a 1). The same applies to columns 5 and 9, with the digits 5 and 9, respectively.
German whispers: Digits on a green line must exhibit a difference of at least 5 from their neighbors along the line.

Solution code: Row 4 and row 9 left to right (18 digits total, no spaces)
