Packed Lunch

Rules:

• Normal sudoku rules apply.


• Sandwich: Clues outside the grid show the sum of the digits sandwiched between the 1 and the 9 in that row or column.


• 159: A digit in column 1 indicates the column in which the digit 1 appears in that row (e.g. if r2c1 is a 4, then r2c4 is a 1). Columns 5 and 9 have the same rule for the digits 5 and 9, respectively.
