Shade some cells such that all unshaded cells are orthogonally connected, and all orthogonally connected groups of shaded cells touch the edge of the grid.
Clues outside the grid indicate the sums of connected groups of either shaded or unshaded numbers in the respective row or column, in order, where numbers in cells with the opposite shading serve as delimeters between groups. All the columns are for one of either shaded or unshaded, and all of the rows are for whichever type of shading the columns is not.
The letters A to J replace the numbers 0 to 9, and no two letters may replace the same number. However, the given letters are all incorrect, and must first be replaced with letters that come one before or one after alphabetically. For all clues, none may have a leading zero.
A 1-7 example is provided:
Solution code: Row 5 followed by Row 8

Yet another amazing puzzle! It's incredible how the puzzle can be so complex, yet so smooth after all the key deductions are found.

I really liked the logic, but it was very hard for me to discover even the easy steps - so basically almost every step in this puzzle :o)) - luckily got there in the end. really well set. my favourite part was how the J clue was determined.

So much fun! Very mathy, which I find difficult at times, but there is a staggering level of clarity and some nice tricks in there :)
