Crypto Japanese Cave (1)
(Published on 11. October 2022, 08:04 by KNT)
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. A question mark can be any number from 0 to 9, and for all clues, none may have a leading zero.
A 1-6 example is provided:
Solution code: Row 7, Row 8

Great puzzle! I usually skip puzzles in penpa, but I just found a tip to play them in the CTC-app (https://marktekfan.github.io/sudokupad-penpa-import/).
Thank you.

Very enjoyable and quite straightforward compared to most of your other puzzles! Nice to see some older rulesets being used again :)
