Normal sudoku rules apply.
Clues outside the grid indicate the sums of the digits in contiguous blocks in that row/column. Cells in blocks should be shaded. Blocks must be separated by at least one unshaded cell.
For best results use pink for shaded and blue for unshaded.
Solution code: Row 3 left to right.
