Doubled Japanese Sums (41)
Instruction:
Place a digit from 1 to 9 into each of the empty cells so that each digit appears at most once in each direction for hex cells. The hex cells are doubled. In the example, a number in a cell eliminates itself from a total of five directions. Shade some cells in the grid such that the numbers outside the grid indicate sums of digits in white cells in the corresponding direction. If there is more than one sum, the given order is valid and there must be at least one shaded cell between the sums. A question mark (?) can be replaced by any non-zero number. Given black cells are separators for the relevant directions.
