Instructions
Fill the grid with digits from the given range, so that each digit appears exactly once in every row and column. Clues outside the grid represent the sum of all formed numbers in the corresponding directions. For example, 424 can be obtained by 423 and 1, or 421 and 3.
Row clues read the numbers from left to right and column clues read the numbers from top to bottom.
